MIXT Energy Shaker Bottle, 16 oz. Shaker Bottle, BPA Free & Lid Mixing Technology (16 oz, Black)

I have to admit I was super skeptical about this because it didn’t have the metal ball, however, this works better than the other shaker cups! It blends protein powder and collagen powder perfectly. It has not leaked wile in my bag commuting or when shaking the contents up. The glow in the dark was a nice bonus!

Great size for my shakes, 16 oz. Seems well made with great results . Excellent product.

Works ok. It does blend, but I feel like it needs a little more shaking than a blender bottle. But it's also cheaper and easier to clean.

As a cup, it works well, mixes G Fuel really well. The only reason I knocked off a star is because I think I would have liked a clear cup to see the water level better. Also, if you over-fill the cup can leak a little bit.Overall, it is a great cup. And, again, it mixes any powdered drink really well.

Works great for mixing powders and liquids. It doesn't leak.

Most of these cups were pretty expensive for what they are I thought. But this was a great price and I was a little worried because it didn’t have a ball but instead a plastic lid piece that mixes it for you but honestly I think it works better than the ball so definitely recommend this cup!

This mixes my protein powder well without a shaker ball. My only complaint is that a plastic film started peeling off all over it after a few weeks. Probably should expect it for such a reasonable price. For me, it's not worth drinking bits of plastic that fall off, so I'm going to switch to a metal bottle or a mason jar with a shaker ball.

This is the best shaker bottle I have ever used. Super easy to clean, mixes powders well and easy to clean.
