Vitamix vs Oster: Which Blender Should You Buy for Ice?

Last updated August 3, 2026 · owner ratings verified July 2026

Which should you buy?

If crushing ice is the whole job, buy the Oster Pro 1200 and put the $300 you saved somewhere useful. If you make smoothies most mornings, buy the Vitamix, because the difference between chopped ice and pulverized ice is the difference between a gritty drink and a smooth one, and no amount of extra blending time on an Oster closes that gap. The two brands are not really competing for the same buyer — they are competing for the same countertop.

How do the blades actually differ?

This is the part that explains everything else. Oster uses sharp multi-point blades that cut — a six-point Dual Direction blade on the Pro 1200 that can reverse to break up a jammed load, and a conventional four-point blade on the Classic Series. Sharp blades chop ice into smaller pieces of ice.

Vitamix uses blunt, laminated stainless blades spun very fast by a much larger motor. They do not cut; they smash. Food is thrown against the blade edge at a speed high enough to destroy cell structure, which is why a Vitamix turns frozen fruit into something with no perceptible texture, and why it can heat soup through friction alone.

For ice specifically, both approaches work — but they produce different results. Oster gives you crushed ice: distinct fine chips, ideal for a cocktail. Vitamix gives you snow, which is what you want in a frozen drink or a smoothie. Neither is wrong; they are different outputs, and knowing which you want settles the purchase. Our category ranking is in the best blender for crushing ice.

Does the glass jar matter?

More than people expect, and it is Oster’s most underrated advantage. Boroclass glass does not scratch, does not cloud, does not retain garlic or onion smells, and does not stain from turmeric or berries — all of which happen to plastic jars over a couple of years. Glass is also heavy enough to stay planted on the counter when the load is unbalanced.

Vitamix uses Tritan copolyester, which is lighter, effectively unbreakable, and specified because a 64 oz. glass jar spinning at Vitamix speeds would be genuinely dangerous. It does scuff over time, and long-term owners do report clouding. Neither material is a mistake — they are consequences of the motor speed each machine runs at.

One practical note: never put ice in a glass jar straight from the freezer and then pour boiling liquid in. Thermal shock cracks even borosilicate glass, and it is the single most common way an Oster jar dies.

How long does each one last?

A Vitamix is a ten-to-twenty-year appliance and the resale market proves it — used machines hold value in a way no other blender does. The 5200 carries a seven-year full warranty and the E310 five years, and full means Vitamix pays shipping both ways and fixes the machine rather than arguing about the container.

An Oster is a three-to-seven-year appliance, and the failure points are known: the jar-to-base gasket weeps, the blade assembly bearing gets rough, and eventually the motor coupling wears. All three are cheap, stocked parts, which is why Oster blenders from the 1970s are still running in some kitchens. The all-metal drive is the reason — it is the component that fails first on nearly every cheap blender, and Oster does not use plastic there.

The honest math: two Oster Pro 1200s over ten years costs about $250 and still leaves you $150 behind a single Vitamix. If you use a blender daily, the Vitamix wins on cost per year as well as on results. If you use it twice a month, it never catches up.

How loud are they?

Both are loud, and the Vitamix is louder. This is not a defect: moving a large blade through a dense load at high speed makes noise, and any machine that pulverizes ice will be unpleasant to stand next to. Vitamix owners who love their machines still list noise as the main complaint, consistently.

The Oster is quieter mainly because it has less motor. If noise genuinely matters — an open-plan apartment, a sleeping baby — neither brand is your answer, and you should be looking at a machine with a sound enclosure, which starts well above the Vitamix price. There are also techniques that help on any blender: fill the jar to at least a third, add liquid before ice, and put the machine on a silicone mat rather than bare stone.

Do you need to add liquid to crush ice?

On an Oster, yes, and this catches people out. Dry ice cubes ride up the sides of the jar above the blade, the load stalls, and the motor labors — which is exactly the condition that eventually strips a drive coupling. Add a quarter-cup of water or juice and the ice circulates down into the blades, and the machine handles it easily.

On a Vitamix the tamper solves the same problem mechanically: you push the load down into the blade while it runs. That is a genuine functional advantage for thick frozen mixtures, nut butters and sorbets, none of which an Oster can make well.

The bottom line

Vitamix is the better machine by every measure except price, and price is not a small consideration at a three-to-five-times gap. Buy the Oster Pro 1200 if you crush ice occasionally and want a food processor thrown in; buy the Vitamix E310 if you blend most days and want a machine that outlives the kitchen. The one purchase we would argue against is a $150 blender with a plastic drive gear, which combines the weaknesses of both.
