Electric Shaker Bottle, 28 oz Blender Bottles, Made with Tritan - BPA Free - Portable Mixer Cup/USB Rechargeable Shaker Cups for Protein Shakes

Product quality is good, but if you have a thick ingredients in your drink it might not mix the drink properly. The motor still feels weak

Please do not purchase this. I used for a few weeks and then later when i tried to charge it.. the motor doesn't finish charging yet. So its damaged .better go for another product. Disappointed currently and looking forward to buy a better product. Dont lose your money buying this.:(

Total waste of money it became a useless cup in a week

As shown in pic but not good to shake protein, returned and get refunded

It's written that it's good for protein, but it's not. Even after a minute of mixing there are still a lot of pieces of protein/gainer in the bottle. Don't waste your time and money if you consider it for sport supplements.

not as mentioned , very poor performance , mixing is not complete

I used it and it finished charging and it no longer charges

I received the item, couldn't charge it. Changed the cable, still not working! I am really upsad! Never again

Protein sticks to the inside a little when trying to wash it, but works good and battery lasts a week. Motor is pretty strong.

My nephew loved it. He said it worked well for him

Bought this as being of a larger size it is easier to clean.

I have been using protein powders for a very long time. My normal mix includes adding yogurt, powder, and fiber. With shaker bottles, I have regularly not been able to get a smooth mixture. I bought one of those ones that you stick into a cup to mix. My wife complained that I made too much of a mess with that. A regular blender is too much of a hassle. So I thought I would try this. I wanted a bottle with a larger volume, and this fit the bill. I now start this up with the liquid (remember hold the button for some time to start), then add the yogurt, then the powder and fiber...mixes great!! And my wife is happier, because no mess in the kitchen.

This cup mixes powdered drinks very well. The power switch is difficult to operate. It frequently takes multiple attempts to power on or off. Also use caution when ordering as the description and photo’s don’t match. I order the pink based on the description but received the blue instead. My husband tossed the box before I was able to return/exchange. The blue is ok but not my first choice.
