I purchased this shaker cup not too long ago. In less that a year the metal attachment at the top of the cup came apart. The lid does not close properly and the plastic closure that goes over the spout has a significant fracture without much use. This product is poorly designed and has completely fallen apart without much use.

It does its job but I rather use a normal shaker and pay less. I use this as a water bottle now lol

I’ve really enjoyed using this shaker bottle. I have a few other bottles, but they aren’t used anymore because I like this one more. I did initially have a problem with it. It wasn’t mixing my supplements very well. I tried shaking the bottle upside down and it works much better now. 

The lid has a strange appearance inside that prevents it from being washed well.  It leaks, and I can't make my smoothies here because I can't wash it well.  works fine for water only.

The cup itself is solid metal and great quality. The design is nice and the imprinted measurements are very nicely done and have not degraded in the slightest. The lid, however, is extremely poorly made. Within a week , the “metal” right around the the lid fell off and you could see where the glue was applied…okay, that’s fine it all still works. However , the flap which seals the bottle, the rounded piece which keeps the bottle sealed for shaking / transport broke off and lodged itself into the spout of the lid. So, now I have a nice cup. Good for smoothies I guess… Poorly made, would not recommend.

When I ordered it I thought it would a metal shaker cup but I find it’s keeps the drink really cold 

Echoing other reviews - the plastic lid split and no longer seals. My older Blender Bottle shakers that get used more often are still in great shape. I appreciate the metal (instead of plastic) body, but until the quality improves, there are better bottles from other companies.

I am glad to be a part of myprotein and i appreciate the services. I like the shaker.

I got the shaker for free when I bought enough powder. Good thing too because the plastic ring on the lid popped off. 

The lid broke within 2 weeks of use. The shaker has a lot of suction which causes the plastic lid to stick to the bottle and break off easily when you’re opening it. The bottle is high quality but the plastic lid is thrash.
