dropped it once on the car park outside the gym and the contents started leaking out like a paddling pool in a darts hall. The gravel tore unrepairable holes immediately.

A great bottle at a great price, does the trick

Can't think of any problems with the shaker I like the compartments at the bottom of the vessel it keeps me well hydrated thank you

Great product!! Like the compartment to store powder and vitamins so you can take on the go. 

Very good and doesn't leak like most others I have tried will defo buy another

Perfect shaker for on the go! Makes sure there’s no lumps and the shake has a good consistency. Can also store an extra scoop of protein and supplements in the bottom!

Bought this needing a larger capacity shaker similar to one i have already and was instantly disappointed upon realising that the main shaker section is 600ml and the 800ML is achieved by including the screw on compartments. Very misleading product description.

Looks cool but, in practice, this shaker does not mix at all. I have other shakers that I rely on and use all the time and bring this one out when the others are in the dishwasher or I'm too lazy to wash them up. I regret it each time. I try and put more water and less powder and shake harder than usual with this shaker and still get dry powder at the top of the opening, and endless amounts of lumps. Terrible, terrible product. Should be discontinued.

..out protein powder.

Its simple but effective, it has a store that I use for haribo after a workout, and another that you can put protein powder in to mix before a workout. It's a good size for my bag. Just make sure it's shut properly before shaking and you're all good :)
