Protein shaker screw top 100% LEAK PROOF drinks bottle 400ml by Musclelinx (Black 400ml)

I have been looking for a small shaker like this for a while. I am very happy with this one. It is the perfect size. Fits even in my purse. Leak proof. Easy to drink, no cap flapping back and fort. Easy to clean. I love it! I have been using it for several months now and no change in performance.

Purchased this for my protein shakes! I didn’t want to use the huge bulky ones as I only use a small amount of liquid. This bottle is the perfect size! I put 200ml water, 1 scoop protein and then top up to the 300ml line water and shake! It’s the perfect consistency!

I have just bought a second one of these, it is just as it is pictured and it is great, I have 200ml of liquid so I don't need a big bulky shaker, and this one I can keep in my lunch bag to keep it cool until I need it.The only downside I will say after quite a few uses is the cap doesn't always screw on perfectly on one side but I just keep screwing the lid down until it shuts completely. It doesn't put me off at all as they are really well made and perfect size.

Greens powder is a pain to mix and you want to chug it in as small a quantity of water as possible as it's so foul. The size and mixing mechanism of this beaker is spot on, and it definitely doesn't leak!

I like the look of it. Yet to use though.

Really a great product, love the size, one minor thing adding Oz scale would make it perfect.

Does everything perfectly. Easier to use and clean compared to large shakers.

It is fiddly to get it closed using the larger top. The small is loose and will probably get lost.
