Smartshake Lite 4 Pack Protein Shaker Bottle 800 ml | 27 oz Leakproof Gym Workout Shaker Bottle, BPA Free Protein Powder Shaker Cup for Men Women(Mist Gray, Army Green, Black, Navy Blue)

Does what it should- Whey protein I use, so i can't comment on thicker protein powders.These are really easy to use, no leaks and great for everyday. Size suits the 1 scoop i need.

I've been using them for a while now, the quality of the bottle is quite good, effortless to clean as well, doesn't leak at all like my previous one, and the size is proper which makes it easier to carry. Overall, it is highly durable.

Great size, mixes different powder shakes well too. Most shaker cups are far too big but these are a great size with a decent spout too.

These are excellent and good value for money. I was dubious about the claim that you don’t need a springy ball to mix the contents of powder-shakes, but they work brilliantly and, dare I say, better than the shakers that require a springy ball.These shakers don’t get the full five stars because some of them are so dark it’s almost impossible to see where the fluid contents are in relation to the measuring marks on the side which very helpfully go up in 50ml steps.So four and probably in truth 4.5 out of 5 from me.

They mix the shake really well and after buckets of runs through the dishwasher they have been fine. The powder cup is a fraction too small for a full 2 scoops, but only by a small amount. Zero leakage

Instead of 4 x 600 ml bottles I received the presumably far cheaper pack of 3 x 400 ml bottles.

You get what you pay for, but these are great little shakers that get the job done on the go. Easy to use and clean.

Great shakers, good size, good quality. The clip attachment is really useful to clip to sports bag when hand are full, and the separate powder pot is also an added bonus.But most importantly they don’t leak! Would definitely buy again!
