You expect a shaker to not leak, however, this one leaks every time I use it. Additionally the colour on the outside has started to peel off after only a few uses, making it look awful. Very disappointed 

Bottle looks great. But peeling on the outside coating off the bottle. Not recommend. I wanted a replacement bottle but it’s not easy to work out how to do that.

I love this flask colour and the metal rather than plastic. but it arrived scratched and often leaks in my bag if it isn't up right 

Love the bottle used 3 times and has started falling apart

The most basic function of a shaker/ drink bottle is being leak proof... this however is not. No matter how tight I screw the lid on it will always leak..
