BlenderBottle Shaker Bottle Pro Series Perfect for Protein Shakes and Pre Workout, 24-Ounce, Black

Does exactly what it should do. An easy bottle that mixes my protein shakes!

Love the rounded bottom. No grit or pieces that missed hitting the blender ball.

As advertised, it does seem leak-proof or at least very leak-resistant. Of course I would be smart and hold the snap top when shaking it just to be safe. As far as cleaning, it is a bit tricky to get inside the screw-rim of the lid. Also, since my bottle is the dark color, it is difficult to see if I cleaned properly inside the main body of the bottle, but that doesnt go against the rating, I would just get a clear color if I were to buy again... and I would buy again. Nice product overall!

Bought this to use for protein shakes. Works better than my smoothie blender or just shaking by hand.

The shaker blends powder well with water, but requires more shaking when using milk. 4 stars because its a little difficult to clean by hand. Its also slightly difficult to dry by hand because of the narrow size. I have to air-dry it, so I dont get to use it everyday due to the cleaning and air-drying process.

We purchased this shaker on a whim as my teenager needed one to pair with the whey protein and mass gainer he was taking. Well we were not disappointed as the lid secures very well so there’s no worry of spill if the shaker gets knocked over, trust me, we tested it. The ball that’s in the shaker breaks down the whey protein really well which is important and saves from having to use a super loud blender. Overall, it’s been a great product and well worth the investment.

Everything was OK, but then suddenly ... cap dont reliable . so , may be, my shaker was defective.

Does a good job of shaking water/milk with powder. I added half of a softish banana. It left some clumps even after shaking vigorously. Shaking more helped but there were still some clumps that you have to just deal with.

Frustrating because it works well but opening and closing it is a huge pain. Might return. It does really well mixing up both my protein drink and my green drink
