Love, love this whipper. Had to finally replace my old one that I got several years ago that was battery operated. This rechargeable replacement is incredible. Thought I would miss my old one, but no. The 3 interchangeable attachments make it my go to for a ton of things. Perfect for mixing protein powders!

Terrific device. Fun to use.

Color: Black

Outstanding. Works incredibly well. And I have now also learned that skim milk makes far better foam than mild with even 1% fat (foam comes from protein and fat inhibits). Anyway, this device is well made, easy to use, two soeeks are great, battery lasts ,one time between charges. Really pleased.

Best frother ever!

Color: Black

I’ve had this frother for over a year now and it’s by far the best I’ve ever had. I purchased others in the past and they would not hold charge or end up not working after a while, but this one holds a charge forever and has lasted well over a year. It’s easy to use and powerful. Highly recommend!
