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

The new shape at the bottom of bottle makes it easier to blend. Super duper.

Love this bottles

After a year of use the lid of the bottle cracked near the back. I used it on weekdays for just over a year before the lid cracked and started leaking. I hand washed it every time so using a dishwasher might make this happen sooner.

It is listed as 24 oz. It definitely is NOT. It only goes up to 18 on the bottle. I did fill a measuring cup with 24 oz of water and you can barely make 22oz fit. But thats to the very top of the rim. Really disappointed in that. It does seem to be leak proof though. I shook it really well and it never leaked.

I like the extra space vs the smaller cup, and the clear plastic option that allows me to see when its time to clean the cup. I also prefer this one, to the version with silicone seals and the locking lid, which my wife has. The standard type lid is easier to close, and clean... Seals just as good as the silicone version.

... I specifically bought this to mix/shake instant pudding as it seemed from description and customer reviews that this would work almost flawlessly. However, my experience was not so. All of the powder did not dissolve (yes, I shook it vigorously and for a long time), and cleaning the mixer thing inside was not as simple as rinsing under a running faucet. So, did not work for my purpose, but I think it would be great for mixing health food drinks; quality seemed to be excellent.

Works great. Mixes well, doesnt leak, easily cleaned. I use it for powdered soy milk. The 24 oz size only holds 16 oz when full to the top (cap off) before mixing. Thats the reason I give it 4 stars. I also bought the 32 oz size, and it hold about 32 oz of water only to brim, so good for 24 oz with the soy milk powder.

I like the design and the way it dissolves my protein shake. It is easy to clean and handle. So far I have no negative comments and have received no benefits for writing this review!
