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

I have been purchasing the pro 32 for maybe 3 years and the classic blender bottles for more. The classic bottles get a film on the inside that is just funky. The pro bottles made me feel more comfortable because they didn’t. I am a special education teacher and am afraid of having a glass water bottle in my classroom (yet plastic is not my preferred thing to drink out of). I thought the pro model had ticked many of the boxes as it didn’t feel filmy or slimy, and the lid sometimes gets some funk if you’re using protein powder, but nothing crazy. Today I noticed my newest bottle has plastic fraying, it is on the inside of the lid (where there shouldn’t be any wear).

It mixed a very difficult protein powder quickly with zero clumps. There were no leaks and it was easy to clean.

The ergonomic design of the cup was great. The inside has a ball to help with mixing. The flaw is the cap does not close tight. You must hold it down to shake up the mixture. Also if it is not screwed on just right it leaks from the top as well.

Just starting up protein shakes again after several years - this is similar to what I had before and it works just as well.

Good size (large enough to mix two scoops of protein) and cleans easily. The taper bottom means that it fits in most car cup holders.

Leak proof protein container

Amazing refinement of a very simple product with great attention to detail. Advertised as leak-proof, easy to clean, and top-rack safe. In my experience it is all of these in concert. For instance, the cap snaps down onto the lid securely before putting in the dishwasher for the first time. After the first time in the top rack, the snap is a little more difficult but it still works. This expresses to me that they took into account the tolerances before and after dishwasher exposure to make sure everything would still fit together. Many powders are gritty, and would be hard to clean out of small crevices. Thankfully the bottom of the inside of the cup is rounded so there are no such crevices. The only things Id change about this product would be to give it a flat outside bottom for easier hand-washing of the outside, and to add smaller fl. oz. increments, but those are just nitpicks. Had it for several months now, and still happy.

Its very solid built & very easy to clean

After a few months, the lid was able to screw on incorrectly, causing it to leak. This is avoidable if you pay extra attention to how it screws on, but its annoying to get careless one day and spill stuff on your clothes. Besides that, one thing I noticed thats different is that the labels for measuring oz starts at 6 and increments by 4s. A bit strange and not my preference, but its not that big a deal

I love this for my workout. I had to replace it after I dropped it, and the bottom blew out.
