Good shaker but the colour on the website is a bit misleading. It looks dark blue, in real life it's purple.

NADINE: a few months ago

Very good shaker...mixes powders very well and no clumps!

Vikki: a few months ago

Good sharper cup that is holding up well to transport in my bag. I can fill with milk before leaving the house and it doesn't leak in my bag. Mixes well and is easy to clean. The labels did come after 1/2 washes but that doesn't effect its function at all.

Really good shaker. If you put the liquids in first then your powder it works really well! The top flip lid is not leakproof you have to hold it while shaking. But it does the job!

Johanne: a few months ago

Just great! No leaks and so easy to clean.

Rachel: a few months ago

Great size and easy to clean both the bottle and the ball. Lid seals tightly and haven't noticed and leaking when it's fallen over.
