Compare Blenders
Oster Pro 1200 Blender with Borosilicate Glass Jar scores higher on safety - here's why.
The most important dimensions, side by side.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want the safest commonly-available jar material (borosilicate glass) with independent third-party BPA verification.
You blend a variety of ingredients including soups, frozen drinks, and sauces and want enough motor power to handle them reliably.
You want a warranty that gives you more than 1 year of coverage without paying Vitamix prices.
You're upgrading from a plastic-jar blender and want a meaningful step up in food-contact safety.
Your household blends daily and needs a mid-power machine that won't give up on tougher recipes.
You're a couple or small family of 1-3 people and the 48oz jar is the right size for your daily blending.
You want proven Vitamix blending quality at the most accessible entry price point in the lineup.
You value a 5-year warranty — above average for the category — on a daily-use appliance.
You blend primarily cold ingredients and are comfortable with Tritan plastic under use-with-caution guidance.
The main thing to know
The Oster Pro 1200 uses a borosilicate glass jar — the safest food-contact material available — but the 48oz capacity requires two batches for a full family of four.
The Vitamix E310 uses a Tritan copolyester jar — brand-named BPA-free, but peer-reviewed evidence shows trace migration under standard conditions, which matters most for hot blending and acidic ingredients.
Skip this if you...
You're choosing between this and a budget glass-jar option only for safety reasons — the $40–$60 alternatives carry the same Mamavation safety rating.
Your priority is ultra-quiet operation — at 1200W, this blender will be audible in open-plan living spaces.
You regularly batch-blend for four or more people and need full 64oz capacity without a second blending round.
You want glass or stainless-steel food-contact surfaces to eliminate plastic concerns entirely.
Neither of these quite what you're looking for?
