I use this to shake my protein and I love it, it doesn’t leak at all and the protein mixes very well. 

Its basically cheap and does the job without any problem. No point in paying alot of money on something that has same quality and does the job exactly the same. All companies take more money for their name these guys dont. Extremely recomended.

Completely confused by any of the positive reviews. The top doesn't stay on and so constantly opens and leaks in bags. Doesn't do its job at all.

Best shaker I’ve used no leak at all, definitely recommend 

Really pleased with this shaker leaves no lumps. Would recommend.

Very good protein shaker, very handy for protein shakes and BCAA's. Only bad thing about the shaker is the writing on the bottle can come off easily if you put it in ur bag and carry it around a lot. Apart from that does everything it needs to do.

Really good for mixing and easy and quick to do, i’d never used one before but this made it super easy for me! Very good price, strong and lightweight. The only thing is the cap to cover the top that folds over the lid looks like in time it may break off, but other than that its great

This is a great shaker, mixes really well, easy to wash up and doesn't leak. Very impressed

This shaker is a great size and the mess style top means you don’t end up with clumps of powder! Nice colour as well, would definitely recommend!

I'm surprised by other reviews saying this is a poor quality shaker. I've found that it's water tight and is a great shaker. Have had no issues with it and would definitely buy again. The price is brilliant, especially when you get it at the reduced price once you're purchasing over a certain amount of other products on the website. The mesh insert is handy when you're putting blended berries into your shake, so that you don't get the "bits" when you're drinking.
