I like this shake that bottle, I bought one for my wife. I also ordered an extra protein shaker bottle today.
People complain that the snap-lock cover will be stuck, but if you hold the protein shaker and point to the phone, just like a phone, this is not a real problem. It will not hinder you.
This Shaker Bottle does exactly what it says. There are no large lumps or fragments on the powder, no leakage or other things that need to be cleaned.
I like this Shaker Bottle!
