They are cheaply made the lid leaks. They are still a decent buy for the price but definitely not a shaker cup for mixing protien or pre workout

I like it better than the ones I’ve spent more on when I buy at chains.

My bottle started to leak after a few uses

Ive been using this for a week now, daily. Ive previously had one of the ball style shakers. PROS: volume of the 12oz is perfect for allowing me to make a full size meal shake with add-ins like fresh fruit, but isnt a huge size so easy to carry. Very simple to clean with the attached shaker element - nothing gets lost/falls out. Snap top is very secure. Measuring lines on the side make it simple to fill. Easy to screw the cap on - would be good for someone with moderate arthritis/poor grip strength as it seals well with gentle pressure without needing to over-tighten before shaking, and the wide rounded size is easy to hold. CONS: drinking spout is a little awkward for me - its a bit too wide. I prefer using a silicon reusable drinking straw with it instead. MIXING MECHANISM: what is no different between the loose metal ball style and this one is you need to put powders in on top of the liquid, or you get a pile of muck at the bottom... the fixed mixer doesnt scrape the sides, so just be aware of how you fill it... I put some liquid, then powder, shake, open, add more liquid and re-shake, to minimize clumping.

Product was just as described. Not exactly sure what kind of material was used for the stickers on the cups but would have been nice to have a little paper with cleaning instructions.

Super cute. I keep one at home and one at work.

Ive used the ball blender bottles for years and have grown tired of losing the wire ball blending mechanism as its rolled off the counter and behind a major appliance after cleaning it, rendering it useless as a blender bottle. Then its months until I can get some brave soul to rearrange my kitchen appliances so I can find & retrieve this blender balls. Usually by that time Ive grown tired of storing the useless bottles and have tossed them out. These bottles havent changed shape on the outside very much. They come in cute eye- catching colors with motivational quotes on the outside to keep you inspired & moving forward. But the real surprise is on the inside... Obviously, someone felt my pain and created these little beauties! They still use a wire mechanism to very effectively whisk your drink, but in this case its been redesigned to be part of the lid structure, rather then a separate piece! The lid now sports a 1/2 pole that extends to the bottom of the bottle when the lid is secured and the multi-level wire whisk is now wrapped securely around this little pole, so when shaking the bottle, the whisk whirs back and forth to blend your drink very quickly and efficiently. This beauty far surpasses the wire ball blenders as its clever redesign allows it to take far less shaking to get your drink powder fully encorporated than ever before! Another bonus is that it only breaks down into 2 separate pieces which are very easy to clean and I havent had any issues with these bottles leaking at all from the top seal or from the mouthpiece seal, which snaps shut firmly. I highly recommend these shaker bottles and I love the more effective, redesigned, attached wire whisk mechanism! This is the Ferrari of shaker bottles! Pick one up for yourself and see the difference it makes in blending one of your hard-to-blend mixes. You wont be sorry!

Works great to mix my thrive shake! No leaks, and dishwasher safe

I like it a lot and it cleans easily
