Game Changer for Coffee Lovers
Color: Storage Cover Black, Size: Rechargeable
I purchased the Circle Joy Rechargeable frother mostly because of the price. The frothy-whipped cream is a treat on the weekends, and the last hand frother I purchased zapped out. WoW - this one is amazing! The last one I had was battery operated, and wasn't as fast as this one. I now use it everyday because it works so quickly. It comes with a "lid" for the blender part, so I can toss in my briefcase. Love that recharges quickly so its ready when I am. Great price, easy to use, looks sleek, and tiny enough to take with you. LOVE, FiVE Stars

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.
