Nice to have a new jar, replacement my 7 year old jar. The bearing had worn out and the jar became too noisy, but it was used almost daily. No complaint, it lasted longer than I expected. Quality materials, sturdy, this FourSide pulverizes anything to a smooth consistency. My only issue is the opening in the lid for this version versus my former lid is too small, difficult to add ingredients and it fits a bit too loose. Ugh!
I loved the new jar and the rubber top is so easy to clean. It is almost like it is non stick. Our old one just wore out. We use ours regularly and no issues. I swear by Blendtec !
