Oster BLSTDG-B 6 Speed Review
Is this the right blender for your kitchen?
The Oster BLSTDG-B 6 Speed is a countertop blender with a 6-cup glass jar, a stainless steel four-point blade, and a motor the listing rates at 475 watts for ice crushing. The one thing that decides whether it’s the right buy is the jar: it’s glass, not plastic. That single choice shapes everything else — how it cleans, how it ages, what it weighs on the counter, and whether you’ll still be happy with it after a few years of daily smoothies.
Buy it if you want a blender you can scrub hard, pour hot soup into, and leave on the counter without worrying about scratches clouding the jar. Skip it if you want a machine that folds away in a cupboard, because glass is heavy and this jar holds 6 cups. If you’d rather have something lighter to lift, look at a blender with a smaller jar or a personal-size model instead — you’ll give up capacity, but you’ll gain easy storage.

Does the 6-cup glass jar make this blender worth buying?
This is the attribute that decides the purchase, so start here. The listing says the jar is 6 cups, dishwasher safe, scratch resistant, and thermal shock tested to withstand extreme temperature. That last claim is the interesting one, because it’s the difference between a jar you treat gently and a jar you can actually use. Thermal shock testing means the glass is checked against sudden temperature swings, so pouring something hot into a cold jar is less of a gamble than it would be with ordinary glass.
Who does that suit? Anyone who makes soup, sauces, or hot blends, and anyone who has watched a plastic jar go cloudy after a few months of tomato and turmeric. Glass doesn’t stain the way plastic can, and the listing’s “scratch resistant” wording speaks to the same idea: the jar should keep looking like a jar.
Where it falls short is weight and storage. A 6-cup jar is a real object on the counter. If your kitchen has shallow cupboards or you blend once a month, that’s a genuine annoyance. The listing doesn’t give a weight for the jar, so if lifting matters to you, check that before ordering.
Who is this blender really for?
The daily smoothie maker. You blend most mornings, you want one button to do the work, and you don’t want to stand there adjusting speed by hand. The listing’s pre-programmed settings and one-touch controls are aimed exactly at you.
The soup and sauce cook. You blend hot mixtures and you want a jar that the listing says is thermal shock tested, so sudden heat isn’t the enemy it is with ordinary glass.
The household with several users. A generously sized jar and a full range of speeds plus pulse means one person can do a coarse chop and another can run it to a puree without changing machines. If more than one person uses the kitchen, that range matters.
Who it’s not for. Someone who blends rarely and needs the machine out of the way. A full-size glass jar is a commitment to counter space, and if you’d have to lift it down from a high shelf every time, you’ll stop using it. A smaller jar or a personal blender fits that life better.

Is 6 cups the right size for what you blend?
Six cups is the number to think about, and it’s worth translating into real jobs. A 6-cup jar handles a full batch of smoothie for two or three people, a pot of soup for a family meal, or a bowl of batter without splitting it into two rounds. That’s the sweet spot for a household that cooks rather than one that just makes a single shake.
Where it’s too much: single servings. If you blend one portion for yourself, you’re filling a large jar a third of the way and washing the whole thing afterward. That’s more cleanup than the job deserves, and it’s the main reason people with small appetites end up leaving a blender in the cupboard.
Where it’s too little: big batch cooking. If you preserve sauce or blend for a crowd, you’ll be refilling the jar more than once, and you’ll feel that.
The listing gives the jar capacity and the blender capacity as two different numbers, so if exact capacity matters for a recipe, confirm which figure applies to the jar you’ll be filling.
How do the 6 speeds and pre-programmed settings work in daily use?
The listing describes two layers of control: six speeds from pulse to puree, and pre-programmed smart settings with one-touch operation. In practice that means you can either press one button and let the machine run a set cycle, or take manual control and pick a speed yourself.
The pre-programmed side is the one that saves you effort. “Takes the guesswork out of blending” is the listing’s own phrasing, and it’s a fair description of what a programmed cycle does: you don’t have to decide when to speed up or slow down. For smoothies and shakes, that’s a genuine convenience, and it’s the setting most people will use most days.
The manual side is for when the programmed cycle isn’t right — a coarse chop, a quick pulse to fold something in, or a job that needs a slower speed at the start. The full range of speeds plus pulse gives you enough range to handle both without a lot of fiddling.
Who finds it fiddly? Anyone who wants total manual control and no presets at all. The pre-programmed buttons are the point of this machine, not an extra. If you’d rather dial every speed yourself, a simpler blender with a single dial suits you better.
What does it ask of you to keep clean?
This is one of the lighter-maintenance blenders, and the listing supports that. The jar is dishwasher safe, which is the big one: you can rinse it, load it, and let the machine do the work. The listing also calls the glass scratch resistant, so you’re not babying the surface the way you might with a plastic jar that clouds and holds onto smells.
The blade is stainless steel, and the listing doesn’t say whether it’s removable. If it isn’t, you’ll be cleaning around it by hand or letting the dishwasher reach it, so check that if a removable blade matters to you.
The base is the part you wipe rather than wash — a damp cloth after spills, and that’s about it. The All Metal Drive is a sealed connection, so there’s no oiling or greasing to do.
What you won’t have to do: replace a jar because it’s scratched, or replace a plastic pitcher every year or two. What you will do: hand-dry the jar if you don’t want water spots on glass, and store it somewhere it won’t get knocked.
Is it built to last?
Two build details stand out, both in the listing’s own words. The first is the All Metal Drive, described as extra durable for a metal-to-metal connection. That’s the coupling between the motor and the blade. A metal-to-metal connection is the listing’s answer to that failure point.
The second is the Crush Pro 4 Blade: stainless steel, four-point design, described as pulverizing and chopping with precision. Stainless steel is the right material for a blade because it resists rust and holds an edge.
The honest trade-off is the jar. The listing describes the jar as scratch resistant and thermal shock tested, and doesn’t mention a replacement-jar program. Plastic won’t shatter, glass won’t scratch — you’re picking which risk you’d rather carry.
The motor is rated at 475 watts for ice crushing, with the listing also giving 700 power watts and 450 blending watts. Those are the manufacturer’s figures, and they describe a motor built for frozen loads rather than light mixing.
How long should it last?
The parts most likely to give out are the ones that move: the blade, the drive coupling, and the motor. The listing addresses two of those directly. The All Metal Drive is described as extra durable with a metal-to-metal connection, which is the design choice that keeps the coupling alive longer than a plastic gear would. The Crush Pro 4 Blade is stainless steel.
The jar is the wildcard. The listing doesn’t state a warranty period or a replacement-jar program. That’s the gap worth closing before you buy, because a blender with a cracked jar is a blender with no job.
The listing doesn’t give a lifespan in years, so treat the metal drive and stainless blade as the durability signals, and confirm the warranty terms yourself.
What happens between unboxing and your first blend?
Setup here is short. Take the jar, blade, lid, and base out of the box, then wash the jar, lid, and blade in warm soapy water or run them through the dishwasher, since the listing gives the jar as dishwasher safe.
Next, seat the jar on the base. The All Metal Drive is a metal-to-metal connection, so it should drop into place rather than need force. Then fit the lid, which the listing describes as having a snap-open spout for serving.
There’s no charging, no pairing, no app, and no registration step described. Plug it in and it’s ready.
How much does the listing document? Not much beyond the parts themselves. There’s no stated assembly sequence or first-use guide in the details given, so if you want a walkthrough, the manufacturer’s own page is the place to look rather than the product listing.
How does it compare with the alternatives?
You’d still blend, but you’d be deciding speeds yourself and replacing a scratched jar sooner.
Against a more elaborate blender: a high-end machine adds more power and more preset programs, and often a larger jar. What it doesn’t add is glass — many high-end blenders use plastic or copolyester jars, so you’d be trading the scratch resistance and thermal shock testing this listing claims for extra capability you may not need.
Against buying nothing: if you already own a blender that works, the honest case for this one is the jar. Glass, dishwasher safe, scratch resistant, thermal shock tested. If your current jar is plastic and cloudy, that’s a real upgrade. If your current jar is glass and fine, you’re paying for speeds and presets, not for a new capability.
The manual method — a whisk, a knife, a potato masher — handles small jobs with nothing but what’s already in your drawer. It doesn’t crush ice or make a smooth puree, and that’s the line where a blender earns its counter space.

What the listing doesn’t tell you
Four things worth confirming before you order, each one a question for the manufacturer’s page or the seller.
What’s the warranty period, and what does it cover? The listing states no warranty length. For a blender with a glass jar, the warranty is your protection against a cracked jar or a failed motor, so it’s the single most important thing to check.
Is the blade removable for cleaning? The listing calls it stainless steel with a four-point design but doesn’t say whether it unscrews or lifts out. If you clean by hand rather than in a dishwasher, that changes your routine.
Can you buy a replacement jar on its own? Glass can break. If a replacement jar isn’t available, a broken jar ends the blender’s life regardless of how well the motor runs.
Which capacity figure applies to the jar — 6 cups or 7? The title says 7-cup and the jar is given as 6 cups. If you’re blending to a recipe volume, confirm which number describes the jar you’ll fill.
Frequently Asked Questions
Does the Oster BLSTDG-B 6 Speed crush ice well?
Yes, by the listing’s own description. The motor is rated at 475 watts for ice crushing, and the Crush Pro 4 Blade uses a stainless steel four-point design the listing says pulverizes and chops with precision. The All Metal Drive adds a metal-to-metal connection between motor and blade. Those are manufacturer claims rather than tested results, but they’re the right features for frozen loads.
What do I have to replace or renew to keep using it?
Nothing on a schedule. There are no filters, no pods, and no consumable parts named in the listing. The jar, blade, lid, and base are the whole machine. The only replacement you might need is a new jar if the glass breaks, and the listing doesn’t state whether one is sold separately, so confirm that with the seller.
Is the 6-cup jar big enough for a family?
For most families, yes. Six cups covers a batch of smoothies for several people or a pot of soup in one go. It’s too large for single servings, where you’d fill a third of the jar and wash all of it. It’s too small for large-scale batch cooking or preserving, where you’d need to refill the jar more than once.
What’s in the box with the blender?
The listing describes the blender, the 6-cup glass jar, the Crush Pro 4 Blade, the lid with snap-open spout, and the base with the motor and controls. It doesn’t list any extra accessories such as a tamper or a second jar, so if you need one of those, check the box contents on the manufacturer’s page before ordering.
Does the glass jar really handle hot liquids?
The listing says the jar is thermal shock tested to withstand extreme temperature, which is the manufacturer’s claim about sudden temperature changes. That’s a meaningful statement for anyone blending soup. It isn’t a licence to move a jar straight from a freezer to boiling water, so follow the manufacturer’s own care instructions rather than testing the limit yourself.
Is a blender like this worth owning at all?
For some kitchens, yes. If you make smoothies, soup, sauces, or crushed ice regularly, a blender does jobs a whisk and a knife can’t, and the dishwasher-safe glass jar keeps the cleanup short. If you blend a few times a year, a manual method or a smaller appliance covers it without taking up counter space. The honest test is how often you’d actually use it.
The verdict
Buy it if you blend most days and you want a glass jar. The dishwasher-safe, scratch-resistant, thermal shock tested jar is the reason to choose this machine over a plastic-jar blender. Add the All Metal Drive, the stainless four-point blade, and the pre-programmed settings, and you have a blender built for daily frozen and hot work.
Buy it if more than one person uses the kitchen. A full range of speeds from pulse to puree plus programmed cycles cover a coarse chop and a fine puree without swapping machines. That range is what makes it work for a household rather than one person with one habit.
Skip it if you blend rarely or you’re short on storage. A 6-cup glass jar is heavy and it takes up room. If you’d have to lift it down from a high shelf, you’ll stop using it, and a smaller or personal blender suits that life better.
Skip it if warranty coverage matters more than the jar. The listing states no warranty period and no replacement-jar program. Confirm both before you order, because a broken glass jar is the one failure this blender can’t work around.
