Absolutely brilliant , can take my protein and my BCAA’s to the gym and it’s all in the shaker ready to go 

There is an additional groove for the sieve. It makes the solution bubble every time u shake it. Suggest to stick to regular bottles sold at this website 

Much more durable than other shakers I’ve had, seems to blend the contents nicely too.

Really impressed with this shaker. The compartments are really handy for keeping my powder separate until ready to use. It doesn’t leak at all and you can have confidence when you shake it that the lid isn’t going to fly open and it mixes brilliantly, not one lump. 

Good quality, easy to clean, quite big,

this is an amazing product, no leaking, love the fact that i can carry my whey protein in the storage compartment! Makes it so much easier for when you are out and about all day and busy! Well worth the buy I love it

Good Quality Shaker, no issues so far. I love the different storage pieces as they really come in handy when going to work/gym.

Received the large smart shaker without the foil over it and it was dirty.

I have experimented with several different shakers. None of which come close to this shaker on achieving a smooth consistency, if you shake for long enough you even get a nice little foam topping. The lid that fits over the spout is very tight- so make sure it is pushed fully down before shaking or you'll get in a mess.

So I was using another protein bottle with a metal ball to break down the powder, however this was still leaving me with bits in my mouth, however I brought this and I have never been left with any protein powder getting stuck between my teeth or anything, what’s great aswell is that you have these compartments which allow you to carry around your supplements without leaving it in the bottle which is really helpful to me as if I need to go to work and want to have a bit of my shake then I can pour a little bit in instead of bringing my big tub which is a pain, so This shaker is a great benefit for everything, please buy!
