HOOPLEShaker Bottle Protein Powder Shake Blender Gym Smoothie Cup, BPA Free, Auto-Flip Leak-Proof Lid, Handle with Ball Included - 24 Ounce

I like the product, The only thing was the description of the product, The description is for a variety pack of shakers (green, red, blue and black) I received 2 green and 2 black shakers. I was disappointed but I did not get what I ordered, but I did not return because I needed the shakers. Had I had the time I would have returned the shakers because of wrong description

The little pins on the sides of the lid tend to break if you drop the bottle on tile accidentally or just when you try opening it on some of them. The ones that still work well are good though

When I first got this cup I absolutely loved it. My old cups always ripped on the top so I thought this one would be better, and it was for a minute. After using it for about 2 months the top stopped closing securely and now I have to hold it closed to shake it like the other cups.

It's a little hard to appreciate the difference between shaker bottles, or for that matter shaker and non-shaker travel bottles. However, this guy works really really well at mixing without making a mess, far better in fact than my $100 lab stirrer that I was using - and of course it's more convenient and can be given a shake anytime.It also has a double good lid lock system to insure the stopper doesn't fling mix everywhere. That would be bad. Just don't forget to fully tighten the screw lid in the first place - because that makes a mess with even a little leak past the threads.The material quality is no-nonsense heavy - easily twice the plastic that a bargain bottle would have. And that's not economizing. It's the last 5% of detail that keeps 95% of the mess from happening.

ok

Like these bottles, they work great for mixing up amino acid drinks, but the little ball and shaking doesn't work so well with protein shakes, no matter how much I shook still had dry bubbles of protein mix.

This appears to be a very good shaker bottle with well thought-out features. I've used it a couple of times so I can't vouch for it's long-term durability but so far it seems sturdy and has performed better than other bottles I have used.Mixes well. The agitator is heavy enough to do the job. It does float as another reviewer mentioned but that keeps it out of the way when you tip it up to drink or pour.No leaks. There is a silicon O-ring in the top that seals it tight and the drinking port snaps shut and then locks with a latching device.Another feature I really like is that on the inside, the bottom is rounded to match the curvature of the mixing agitator that bounces around when you shake the bottle. That curvature helps insure that all of the powder you are mixing gets mixed instead of collecting in the corners like it can on other bottles.One small thing that could be improved is that the measurements etched on the side are hard to see. I fixed that by marking the outside of the container at the levels I usually use when mixing.

Bought this product to carry smoothies to work. It worked out great and love the locking feature. 👍🏾👍🏾Two thumbs up.
