I got this for my husband and he loves it. He said that sometimes it leaks though. Maybe we were sent a bad one but oh well.
Foam on the bottom peeled off revealing rusting, cheap screws after a couple uses. Isn't insulated, sweats badly. Bottom protein holder is cheap, the plastic spins in place when trying to screw on or off. Lid doesn't leak though, so it still works. Not total junk, I'd say it's a 90% fail.
Great material Won’t take a shit on you.
I have been using the shaking almost daily since it was deliver for my coffe ad protein breakfast, and it is great, the lid is a bit difficult to screw to the shaker and the coil spring is really useful when dissolving the protein, and watch out with hot liquids.
