Came free with my last order, noticed immediately the cap comes off (the hinge part in the lid seems like it isn't tight enough to the white cap piece so the whole cap comes off). The cap itself seals fine even without the hinge working so I gave it a try just filled with water (I didn't trust it enough to try it with a other more valuable fluid). Of course, the seal on the black screw top is nowhere near tight enough and it leaks. From unboxing to binning it, this awful product lasted roughly 45 seconds. They're probably trying to get rid of these by shipping them out as free "gifts". I really hope nobody pays actual money for one of these.

Green shaker, clear measurements so can get the correct quantity, mixes the protein powders well. Would Highly recommend 

I’ve herb using this shaker and I’ve found it to be nice and durable and to date still hasn’t leaked or accidentally opened in my gym back just of yet 

amazing product, easy to clean  , good for pre workout /protein / water , strong lid which is good as there are no leaks . 

Got the free plastic shaker after purchasing the whey protein and it is great. I use it to drink electrolyte when I'm at the gym.
