I have had my vitamix for years and I love it. Less excited about some parts of the new product. The travel cups work well and hold a decent amount. It still blends like you would expect. However the part that attaches to the vitamix is clunky and not well designed. If you have a leak it will leak out the bottom. Also the side walls are incredibly high and I think it could be trimmed by a ton. Maybe there is an additional purpose but I can’t see what that could be.
