Cyclone IMPROVED v2.0 USB Rechargeable Protein Vortex Portable Mixer | BPA-FREE Shaker Bottle Blender, Stainless Steel

You see a lot of cheap knick off brands of items similar to this, but they are chargeable and made with poor quality. Spend the extra dollars to get this one, I use mine all the time!

This was just ok while it lasted. The motor was weak to say the least with having issues mixing 2 ounces of water for a test. During real life usage, the device would stop working all together. I would say out of the roughly 30 times I used it there were only a handful of occasions that no issues were experienced. Hopefully it is only mine having this, but in my opinion I would not recommend

Love the idea, the complany was fine to work with but the third time I used the top leaked so I returned it. I was using for coffee and some of the blenders specifically say that they are not good for coffee but this one didn't. So, I don't know if it was the product or simply that it wasn't good for hot coffee. Since I bought it for blending hot coffee it wasn't going to work for me. With that understanding I gave it two stars. Might be great for a protein shake.

Has a strange proprietary USB charging cable. USB to plug into computer or power adapter, but a round plug into the base. If you lose this cable the device will go into the trash. You won't be able charge it. It's odd because it would be easier and cheaper to manufacture this with a standard micro USB. Hopefully they'll fix it

It's very powerful! The only problems i have is the button to turn it on is kind of hard to push all the way in without long nails or what not. Also the little rubbee guard that closes the port to charge the base, is a little flimsy and will probably end up broken soon. Still a nice mixer for half the price of the promixx (the original automatic blender cup).

Its worth having it its a good protien mixer but you can only mix one scoop at time and dont put 2 scoop it will stop mixing it other then its ok

I used this product twice in a row and after the third try it no longer would hold a charge and had to keep it plugged in to use it finally it totally crapped out and would not work at all

This portable blender does an great job with protien powders. I can easily and quietly blend my protein anywhere. I highly recommend this device to anyone especially athletes who are making proteins shakes all the time. Leaves no lumps or clumps in the mix.
