90oz WildSide+ Jar Replacement Compatible with Blendtec Blender, Commercial Grade - Five-Sided Replacement Blender Jar,Kitchen Container Pitcher Jar for Most Blendtec Blenders

This blender cup fits perfect and tge top it came with is much better than the one that came with the blender when we bought it 10/10 will purchase again

I really wanted to love this blender. Unfortunately I had to send it back because the lid doesn't seal well and liquids came spewing out the first time I used it. It also doesn't fit the base tight enough and shakes when in use.

Great alternative to original, works good. It is a little louder than original bottle.

My old Blendtec pitcher was leaking due to a faulty gasket. I saw good reviews on this product. So I thougth I'd give it a chance.It is about as good a quality as my blendtec pitcher. It is much larger (52 oz at top mark vs. 32 oz) than my blendtec pitcher. And it has worked for about a dozen or so smoothies.Two drawbacks:1) The gear fitting at the bottom is a little too snug and straight. It takes a bit of moving and twisting to get it in. The gear at the bottom of the pitcher is supposed to have a bit of a fillet to guide it into the slot. This one has either a very low tolerance, or has no "guide".2) The base of the plastic itself is a little wobbly. I have to hold my hand on top even at low speeds. But if you do that anyway, then no worries.

It works. Three stars due to the excessive price for the item.
