Would be perfect if it didn't leak and mixed the show well. It's true to it's word with it helping the stinky protein odour smell, also great for keeping your shake cooler for longer. However, after using only times it started to leak so can no longer use. The mixer is also rubbish I had to add my own metal coil to blend my protein properly.

The metal ones are easier to keep clean and also keep your drink or shake cooler for longer. great build quality

Does a good job at eliminating odours from protein mixes to mypre workout,had this for 1 month now and is very durable being kicked about in bottoms of bag,cap is solid has no leaks as yet keeps drinks colder, but the bad points are label came off after 2 days on my hand and the mixing isn’t good as there’s only few blades on lid better mix happens in old plastic shaker overall not a bad shaker for mypre mixes but not for protein mixes.

So easy to clean, definitely worth spending a little more because the plastics ones do change colour after time. This also keeps the water slightly more cooler during workout. I love it.

No leak problem is found, just make sure you close it properly. The logo starts to disappear within a month. A major problem for me is the flip open lid doesn't tough as they said. It was torn. Hot water washable is a good thing I like of it.
