I love my new shaker bottle. The design is very cool; the bottle is extremely light, see-through plastic still allows you to see how much liquid is inside, but is nicely tinned. The top lid clicks close with perfect no leak seal, and the inner round mesh sitting just below the top rim of the bottle ensures your protein powder is well blended + stops the empty bottle from rattling when being carried around. I don't use the detachable bottom compartment but it is a nice addition for anyone who needs to carry around another portion of protein powder or other supplements. I'd buy it again & again. It's the best one I've had. I add a photo of the actual mesh sieve as it's missing from the website.
