USB Rechargeable High Power Electric Protein Mixer - Portable Electric Vortex Mixer and Shaker Bottle

Easy to use... you can charge it in your car it comes with a USB cord. Love it. But if you want to add fruit it's not powerful enough if you just want your protein shake and water or juice it's great

Edit: This is broken after a few weeks. Wouldn't buy again..This is a good product. I bought 2, home and office. They work well. My only notes regard the power supply, and the mouth.The provided cord is a usb connection, it comes with no wall plug, and the other end is a pin style connector instead of a micro usb so I can't use any of the hundreds of other chargers I have for it. The mouth isn't quite large enough to take a natural drink from without 'glugging'.The charge lasts a good long time, it mixes my powder very well, and has easy clean up. I have recommended this cup to friends, and so, here I recommend it to you.

I'm giving it a 4 because it overall please me. It has the measurements and blends quietly and efficiently. But the first day I went to open its charger port to charge it fully and the ruler cover piece completely came off and I had to try and search my car for it. So now my charger port is completely open 24/7. I wasnt even opening it hard or anything it just broke right off the bat. I wish I could just get the charder thing fixed but besides that it's a great product.

Bought this for my teenage son for Christmas.I wanted to wait a while so I could see how this lasts.Mixes powders very well and easy to clean after using.The charge on it last a few weeks of using. We just charge it once a week.You can take the base off and charge by itself. Then finish your drink.I recommend this to everyone.

I used this for everything; protein shakes, iced tea, kool-aid. I bought 3. Each one, the motor burnt out a little after a month or 2. When it works, it works great! Which is why I bought 3. When the motor stopped working on the first one, and the amazon return window expired, I disassembled the mixer to find that solder connecting the motor to the battery came loose. When my second vortex stopped working, there was some condensation inside the motor. When cleaning, I never submerged it under water, I would just add soap and about 8 oz of warm/hot water, run the mixer, then detach the motor, before the final rinse. After the third one stopped working, I gave up on this.

Really cool. A little loud when you first turn it on and then it quiets down with a good vortex and then silent with the lid on. The bad is that the motor barely lasts 30 seconds before it starts to slow down and then stop. It seems that the powder still gets mixed in well enough but it would be cool if it would spin for a longer period. Also, I only fill it to about 8 oz and the vortex reaches the rim, wouldn't really recommend putting more than that unless you want a mess.

Love it for making shakes on the go. Really convenient; a full charge lasts me about a week and that's with frequent usage! Holds a good amount of liquid. My co workers bug out when they see it on my desk blending wirelessly LoL " Hey where can I get one of those? "

Overall wonderful product. After having initial reservations, I am extremely pleased having purchased this product. It is the perfect product for mixing protein shakes without having clumps of the powder left unmixed (as long as you follow the instructions! I messed up the first time). It's a quality product; however, my only criticism of it is that the mouth spout is a little small.
