The lid ring came off after using it 3 times. This shaker is made of a metal. This means the shaker becomes really cold or hot depends on what you put in. I wouldn't buy it again.

After having the shaker for a couple of weeks the plastic lid snapped and was unusable, and the paint started to chip off after two washes by hand, I would not recommend getting this shaker!!

It arrived as expected it's good but I can see little scratches on the shaker. For me it's nothing very important as long as it works it's pretty cool but when I shake, a little liquid comes out and that is pretty bad ! For this price, I hopped for better quality...

Instead of a ball that shakes around to mix up the drink, the mixing part of the cup is built into the cap, which I like about it. Keeps my drinks cool, and for the price (I got it for 7.50 during black friday), well worth it.

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.

It worked great for a few weeks but all the paint strips off and the plastic lid cracked and was unusable 

It’s not double walled. If you’re putting in cold liquids it will freeze your hands. It’s pretty though. 

The bottle doesn't have a complete seal, even when fully closed, leaks occur. Good quality material, lid is plastic, bottle looks to be aluminum. Light and durable.

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.

Leaks very easily plus black paint coming off everywhere now looks sh!t
