The Classical Vortex Mixer,Electric Portable Protein Mixer Shaker Bottle, USB Rechargeable Protein Shaker / Blender Bottle with X-blade Technology,100% Leak-proof Guarantee,450ml/16oz BPA-free

Crap product. I have another blender by Promixx that works great. I thought I’d give this one a try and it was a mistake. Buy Promixx! This blender broken the first time I used it and spit my drink all over my kitchen. Big mistake

Very 、very、 very good！

Works great, very impressed

Works OK I guess not much power to it

works well

It was the bad quality, i havent worked and i had used it for 1 week.:(

Mixes powdered protein shake well.

I was excited to get this for mixing my coffee drinks at work easily. However, after using it twice, it began leaking out the top. I tried everything to fix it. The lid was on perfectly, the sealing ring was intact, etc. I noticed cracks along the top edge of the cup, where the lid locks in. I'm disappointed and will be returning this item.
