When I first got this best protein shaker bottle, I was completely satisfied. It is portable and mixes my protein better than any electric shaker cup I have ever used. The only thing I found troublesome for the first 3 months was the clean up.
I never put the electric blender shaker in the dishwasher and always washed the electric shaker by hand. i handled this carefully to prolong the life of the protein shake blender bottle. When this thing works, it works well and I love this product.
