The lid has a built-in shaker cone, which makes it hard to clean. Also, the shaker cap doesn't tightly close, making it leaky if not held upright.

It works great for mixing drinks. I love that it is stainless and easier to clean. The lid is awesome. I wish I had bought more than one now.

I really like the metal shaker but the plastic lid lets it down. I haven’t had this for long and the plastic on the lid has broken so I now can’t use it. I’ll contact MP and see what they say. But on the plus side it’s a good size, keeps drinks cool and easy to clean 

As its looks suggest this is a very durable shaker and it doesn't hold any bad smell after so much use of it ... Thanks my protein

Very good product and easy to clean and use. Excellent 👍

I like the quality of the materials, eg nice metal and design and is a decent size; you can get about 750ml in it. There is a set of measuring markers on the side too so you can more easily see how much water or liquid you are putting in it. Unfortunately my main gripe with it is that the lid has the shaker cone, which is often separable on other shakers, built in. This means that it is difficult to wash by hand and excess protein shake can get stuck in these awkward places, so you need to rinse this straight away after use to maintain it. I haven't used it with a dish washer so can't comment on that.

Perfect size, keeps all drinks cool for hours. Happily take this on walks or refill at work. Make sure when shaking protein the lid is clicked down fully  (had a near miss when I first used it) 

This is best for protein shakes and blends. Easy to handle and clean as well.

the quality of the shaker is quite good and has a nice finishing. The only and major demerit is that when I shake it, liquid keeps leaking from near the sides even after fitting the lid quite lightly. Would love to get a replacement. 

As a water/eaa/bcaa container its brilliant and really helps to keep your drink cold and fresh. I even use it at home for cold water as it has helped me increase my intake by being cool/fresh for longer. I've never had a leak problem so it seals well for me. The lid is the problem. The integrated mixer is fixed to the inside and is not easy to clean or dry but it can be done. The pop up/flip piece is the major issue on mine as it popped out - when closed I can see inside the shaker. I have lots of the standard shakers and owned them for years longer - the pop up/flip (white) has never failed so the plastic material is 100% different. I took one off an old shaker as I prefer the metal.
