Bought for my young Son & its "cool" enough to use! Great little mixing beaker, easy to pop lid off, great size mixing ball & no leakage - just the right size to get a post workout shake in. Have popped in the dishwasher but generally wash by hand as its so easy to clean.

Perfect size not too big. Haven't experienced any issues with lid. Touquieose top is nice too. Comes with metal thing to shake (not in photo).

The blending ball inside the shaker makes this! Best way to describe it, it's like having a mini whisk loose in the shaker. It blends it so well to a lump free consistency and the size is perfect for me. Regarding the seal issues that have been previously mentioned. Mine needs a very firm push to hear the click that the mouth spout is sealed, it is stiff but I can open it.

I brought this because I needed a  shaker.  After using it once I found it really hard to take the lid off to drink out of.  Second time the lid wouldn’t close so there was no way I could use it again.  Shocking! So it went in the bin.  Do not buy!  Very disappointed 

Mixes the protein shake well, but the lid doesn’t fit properly so you have to really squeeze it tight when shaking to avoid leaks. Definitely couldn’t put it in your bag for an on the go shake.
