This product is NOT HIGH QUALITY. It is a very cheap plastic and not suited for high usage for a blender. I would also not use this for hot liquids like blending soups. The description of the product is misleading and the seller ha srefused to acknowledge the issue. I requested a 50% refund to be fair to them as I did receive the product - but they have point blank refused. This product is inferior quality.
Seems good and a lot more quiet than the old one i had from biolomix. my only ptoblem with it is that it doesn't sit tight and turns a little bit when you place it on the blenders base. not a big deal, i recommend!
