Thunderballs Mixing Balls for Your Protein Shaker Cup (6-Piece, Red,White,Black)…

I almost never write reviews but after using these for three weeks in my protein shakes daily, I have to say they work awesome! I put three of these in my yeti cup, water first, then yogurt, then a large scoop of powder. Close everything up, shake it and these get everything so smooth you wouldn’t even know that there’s powder in there. I’m really happy that I can use my yeti cup and not have to buy a special cup just for protein shakes. I have not found that powder get stuck in the little hole in the middle, but I shake pretty hard when making my shakes. And I always make sure these are in first, then water, then the powder so the powder actually isn’t sitting dry on top of these. When I clean I also wash them right in the cup I fill the cup with soap and water and again shake them really hard to get every nook and cranny of these clean. Works mint, never had an issue with powder in the middle. Would highly suggest these for use in any kind of cup that has a solid lid.

These work great! I wanted to move to something a little less frustrating than the metal wire balls that get tangled in the drawer or dishwasher, and also wanted to stop collecting cheap plastic blender bottles that sweat everywhere. I use these in my Yeti bottle as well as other stainless steel bottles, and they seem to mix my shakes better than the wire balls. My typical shake will have 2 scoops or protein, 1 scoop of super greens, and 1 scoop of creatine and these balls mix it all extremely well. Toss them in the dishwasher and they are clean. No untangling!

Bought these to replace the generic metal spiral wisk ball (whatever you call it, you know what i'm talking about) shakers and wanted to try something different. These work well, I have only used 2 at a time I do not think 1 would be enough for the protein shakes I use it for. I like that they float when not being shaken so i can take them out before drinking(unless you like 2 balls hitting you in the face while you try to enjoy your protein shake). These are smaller than you think they are going to be but still gets job done. I also like the hole in the middle, no problems with protein globs getting stuck in there like i feared and in the dishwasher you can just stick them on the spoke.Most importantly I have not yet accidentally tossed these out in the garbage by mistake like the metal spiral wisk ball

These work great. I've used a bunch of different blender bottles and I honestly think these work better than the steel blender balls or the pastic 'Jaxx' style blenders.The fact that you get three of these for less than the cost of a sigle blender bottle is pretty cool. I use these in a Nalgene bottle and they're perfect. Basically they will work with just about any wide mouth bottle, including a bunch of bottle that reguar blender balls won't fit in. They're smaller than standard blender balls, maybe only a little more than an inch in diameter. Still, they blend better than the bigger ones. Plus no rust.Bottom line, I would happily buy these again.

these little mixing balls don't really break up all the protein clumps. They work pretty well with the lighter Whey protein, but they don't work too well with the larger/thicker Casein protein powders. I normally use 2 mixing balls in my 20oz bottle (and a couple of cubes of ice on occasion if my water isn't cold enough). The Whey breaks down pretty smoothly, but the smaller lumps sometimes remains. The Casein protein always has lumps left (I normally use double the water for Casein compared to Whey protein). Still a lot better then using no mixer ball, but an electric blender still seems best for the thicker protein powders.These little guys seem easy enough to clean, big enough to not slip out of the bottle's spout, and small enough to agitate some of the powder in the edges. Although I did have powder that didn't get mixed in from the bottom edges of the bottle once, but that's probably because the bottom wasn't all the way dry

These work great. The are just buoyant enough to float to the top and clean out any powder that does not get mixed and are just the right weight to bounce around and mix up nicely. I will buy more to share with friends as they work really good. Pair these with a contigo ContigoContigo Shake & Go Fit Mixer Bottle, 28 oz., Carolina Blue and you have the best system I have ever used. I have spent over $200 buying bottles trying to find the right one. The contigo with the nutribomb mixing bowls are a perfect match.

I was really hoping to like these, but they just do a terrible job of mixing protein powder. Almost as if they're not even in the bottle. No matter how hard/long i shake it, there are still chunks of powder in the bottle when i go to drink it. I've even tried adding more water than recommended per serving and it still has trouble. Will be looking for something else.

These balls are so light that they float on the top of the liquid, unlike most shaker balls that sink to the bottom. At first I thought this was an issue but I found that for me it work better. The ball is on top where the powder rests and seems to work better for blending things together and making sure there aren't 'chunks' of powder. And you get six for the price. Great product.
