Helimix 1.5 Vortex Blender Shaker Bottle Holds Upto 20oz | No Blending Ball or Whisk | USA Made | Portable Pre Workout Whey Protein Drink Shaker Cup | Mixes Cocktails Smoothies Shakes | Top Rack Safe

Great product. Does exactly what it says. It makes smooth protein shakes with no lumps. I've used mamy shakers with mixing balls which are nowhere near as effective. I rarely write reviews but it is so good. Highly recommend.

Design and its working is really cool, practical. Not much effort to mix the whey protein powder. Does the job very well and no need of a mixer ball inside. Very satisfied with the purchase.

Works unexpectedly well, used with whey protein and milk, make sure to add liquid first then powder, absolutely 0 clumps ..10/10

Excellent, sturdy and compact and works as described very pleased with my purchase

I was very skeptical after seeing one video review of a fella Shaking and it still being lumpy. But he was using the big cup with it only being half full after Shaking. But the rest if the reviews were great. I'm pretty sure in order for the bottles physics to work, you have to have the appropriate amount of liquid and powder. So for example, for me with the small bottle, I used exactly Whey protein and used exactly what they suggest, 1 scoop, 240ml (I out milk instead of water) and shook for 30+ seconds. That filled the cup up perfectly full If you have the bigger cup, I would imagine you'll want 2 scoops and 480ml of liquid. I would imagine having too little liquid in the bottles would essentially remove the way the bottle works, since there would be too much space for the liquid to move, rather than being filtered by the spirals

Really sturdy item and mixes powder supplements quickly and no lumps at all, and without a wire ball! Leak proof, easy to clean

I won't buy anything else now

Unfortunately some clumps remain. I’m giving it three stars because it’s small, nice and may have reduced some clumps, but it didn’t get rid of them. If it weren’t still usable as a shaker and compact, I would have given one star since I mainly bought it for the clumps. Not worth the money.
