Stainless Steel Protein Shaker Bottle with Stirring Ball Durable Fitness Motion Kettle Leak-Proof Double Scale Water Bottle ，700 ml + 200 ml

It does what a shaker should, although, the metal ring on the lid has come off.

Excellent product..I love it

This shaker is pretty great to be honest. it doesn't leak at all and the powder mixes fully with your liquid, I feel the addition of the separate grid in the lid makes a difference to be honest; you still have to shake for about a minute or so.. I like to shake for a good minute then let it sit for a a minute or so, swizzle it round then finish off with one last shake. I never use the compartment at the bottom to contain the powder though because this really adds some size onto the shaker itself and I really don't want it so big to be honest so I just keep the powder in the shaker and add water when I need to. That would be my only complaint if you can call it all so all in all a great product.
