Great for short term
Color: Storage Cover Black, Size: Rechargeable
Works great when it works.... But I've bought three this year and two of them just unexpectedly died with no logical reason. Giving up and trying a new brand for my protein coffee drinks. *Edit....after original review the seller offered a refund and apologized for the issues I had. Bumping up my rating for proactive customer service and trying to make things right.

Great buy!
Color: Storage Cover Black, Size: Rechargeable
Great product. I'm glad I bought this to replace my old, cheap one that I got from Ikea. I like that it has double whisk as it does froth my liquids really well. I like the speed of it and it's easy to use and wash. The battery life is pretty long as well. I haven't charged it since I got it.

Pretty darn good frother...
Color: Storage Cover Black, Size: Rechargeable
This is a pretty darn good frother/whisk, which we use primarily for mixing Crystal Light and LMNT drinks. It holds a charge for a long time and it is easy to recharge with the USB-C port and cable. My only complaint is that you must hold the power button continuously while operating it which is challenging to do using tall cups. It would be much better if is was a two stage on-off switch and had a longer wand, which isn't as long as it could be. But the unit is lightweight, easy to use and very versatile. Overall, I would buy it again.

Works great!
Color: Storage Cover Black, Size: Rechargeable
I bought this because the frother I had was very weak. Even with new batteries, it just never had much oomph. I liked the idea of it being rechargeable and no more batteries! I expected to have to charge it when it came, but it had full power. I have used it every day since it arrived, and it hasn't slowed down a bit. It is easy to use, just pushing down with my thumb on the top. I also love that it has a lid/case. When I bring it on a trip it is fully protected from damage. I highly recommend this frother. It is the best one I have had - and I have had quite a few.

Perfect frother!
Works like a charm. I bought it on a whim to spend less money on lattes! Takes some time to get the angle and right amount of foam, but it is worth every penny. Holds a charge, easy to rinse clean and feels like a little treat every time I use it. Easy to store with its stand, super fast.
