Plastic Blending Mixing Ball Bottle Balls for Sports Drink Protein Shaker Cup Bottle Mixers Better Than Wire Whisk (6 pc)

I bought these to use in my metal YETI Rambler bottle thinking they wouldn't scratch the inside as much as the metal ball type. Bottom line is they don't work--see picture.

They are junk they float and don't mix anything. They aren't silicone they're just abs plastic. Don't buy they aren't safe for food use and human consumption. They are not made from food grade materials and are just plastic molds like the silicone ones. But don't work like them. They're hard and hollow, and they float not wat u need for a mixer in ur protein shake or any shake. Go get the shakesphere it's amazing and works like a charm no ball needed, just the shape of the cup pod does the mixing for u. Any soft foods will blend up in it. Crazy! And it's a lil work out too getting it all blended up. Haha nah jk it's easy

Have enough water bottles that I didn't need to buy anymore of the blender shaker bottles just wanted something I could throw in my own tervis bottles with protein powder. So happy I found these! They work great, mix up my protein and water in some of my favorite water bottles instead of those clunky blender bottles.

Not a small as expected. These are what came up when searching for extra small blender balls. It was hard to judge from the picture and there were no measurements. They did not fit the glasses I needed them to. I returned them - easy enough with amazon. They seem to be decent quality though. I liked that the were dishwasher safe. Too bad they didn’t work because they would have been perfect.

Was expecting mixer balls that were just like the ones that come with Contigo mixer bottles. What I received were items of approximately the same diameter, but just a fraction of the weight. I don't think these work as well because they are so light that they are unable to break up clumps of solids. I would not recommend these.

I was a little iffy about these when I ordered them but I love them!! They work great and you don't have to worry about that nasty metal aftertaste from the metal mixing balls. So happy with them and I used them in hot (bullet proof coffee) and cold drinks. 😊

Works great, super sturdy and so much easier and faster to clean then a wire ball. They seem to have a bit of a different concept then the wire mixer balls in that it seems you are supposed to use multiple mixer balls, as they are smaller. 2 seems about perfect for a standard shake container, but you then have the option of using one for a smaller container or 3 if you have a larger container.

I absolutely love this product. I like to drink matcha on the go and this ball whisk is very effective in making sure the powder doesn't clump together. I just add a few teaspoons of matcha powder to my bottle of water, add the ball whisk to the bottle, and I'm good to go. An additional pro is that after about 30 seconds of shaking the bottle, the tea is frothy, just like it was whisked it in a bowl. I highly recommend this product!
