The shakers advertisement is misleading, with it reporting "Crafted from 100% stainless steel". The base of it in fact is, but the rest is plastic. Only the body is metal. The lid is plastic, and has a non-removable mixer, which is very difficult to clean and will get very smelly very quickly. The lid also just is a regular lid, with a metal ring around the outside that comes off quite easily and after a few washes, as well as the paint. Overall, I would not recommend, especially if you're looking for a shaker that is not plastic, like I was.

This is way better than normal shaker it works so well and leaves no lumps and comes out smooth it also keeps your drinks cold for much longer as it’s metal it go’s so well with clear whey protein it tastes amazing and so refreshing.

Thought these shakers looked like a great plastic free option, however I was disappointed when they arrived. Where the product is advertised as 100% stainless steel, this only refers to the cup part of the shaker. The lid is mostly plastic with a metal ring around and what appears to be a silicone seal. This was a big let down for me as the main driver behind this purchase was because I thought I had found a plastic-free alternative (not to mention excessive plastic packaging). The product description or the product itself doesn't say whether it is dishwasher safe, however I can say after only a couple of goes in the dishwasher I would not recommend. The metal ring on the lid came completely loose after a single wash and the black coating started to peel away. Overall though, in terms of function, this shaker is as good as any. I like that the mixer is integrated into the lid rather than a ball, however this part would be very difficult to clean without a dishwasher. The shaker is also bigger than advertised, closer to 850ml capacity which I like.

Mine arrived with a few dents and got a refund for it. The service is extremely nice and efficient. Otherwise, the bottle is nice itself; stainless steel and leak-proof. Recommended!
