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 regularly batch-blend for six or more people and need the largest available jar capacity in the category.
You want top-tier blending power for dense ingredients like whole nuts, frozen bananas, and fibrous greens.
You value an 8-year warranty and view this as a decade-long kitchen investment.
You primarily blend cold ingredients and are comfortable with Tritan plastic under use-with-caution guidance.
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.
The main thing to know
The Blendtec uses a Tritan copolyester jar — brand-named BPA-free, but independent research has found trace chemical migration from Tritan under standard conditions, especially with hot soups and acidic foods.
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.
Skip this if you...
You blend hot soups or acidic ingredients regularly, as independent research advises against this with Tritan jars.
Noise in the kitchen is a concern and you need a confirmed decibel rating before buying.
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.
Neither of these quite what you're looking for?
