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

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? "

Only buy this if you are using liquid and powder nothing more. Very slow spin, but it works. This is not scalable to other items unless you want to get frustrated. This is an okay purchase.

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

Dead on arrival. Never worked. Charged it up, and it never turned on. Returned it. Keep it. Don't want a replacement.

It brakes very easily, very useful but unfortunately not good quality.

Works great do not like that you have to remove the little cap inside other then that its amazing works with out feeling forced

I bought this bottle one month ago. It is amazing. i love it.

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.
