CLA JLT Shaker Bottle Protein 16-Ounce Storage for Powder Workout Gym Wire Whisk Balls (pink+green (2PCS))

These are a nice size for protein drinks. They are small enough to fit in a mini-fridge, which is what my son does with them.... keeps water in them, then uses that cold water to make his drink. If you screw the lid on tight and shut the small lid on spout tight, no problems with leaks. Of course if you don't, what would you expect but to have some leaking? Overall a great buy and these are used every day. In fact, after buying 2 and using them awhile, came back and bought two more.

These plastic mixer bottles are great! The lid tightens down securely and the opening snaps tightly so when you shake it, there are no leaks. It comes with a coil ball to help in good mixing. I use one for a quick protien shake the other one for pancake mix.

I recently discovered powdered chai tea mix, and these bottles are a life saver in mixing the powder up properly! It makes for a super smooth chai tea that no one knows is from a powder! Prior to that, it could be a bit gritty and I wasn't going to serve that to anyone. This is a great set of shakers that I highly recommend!

I have these cups for my kiddos and I have bought other brands because they are easy to close and shake. Unfortunately, this brand is much harder for my children to close, which results in liquid splashing all over the kitchen. I don’t recommend these for kids due to the lids being difficult for them. Even my 9yo has trouble closing them.

Both leak. Not good when you are drinking your shake at work and it drips down your shirt. I learned, I bought the cheapest and they both leak. Makes a mess.

These bottles are cheap and work great most the time. Every once in a while they’ll leak a bit when I shake them but other than that, they get the job done.

These work great , my husband needed a smaller shacker cup for his lunch box , these are great they hold 8-12 oz ! Very happy with these cups!!!

This was an economically friendly purchase but you can tell in that it is difficult to get the top on easily

Really good quality, exactly what I wanted
