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.

Works way better than its price would suggest
Color: Storage Cover Black, Size: Rechargeable
A family member got frothed milk in their coffee and loved it, so they started doing it at home. They were using a wand mixer which is great at splashing milk all over creation but not very good at actually frothing it.
I asked them what kind of frother they wanted and they gave me 2 criteria: Rechargeable, and inexpensive. They didn't want to spend a lot on something they might not like or might outgrow, and they didn't want to constantly be looking for batteries.
This frother fits the bill. It recharges with a regular USB-C cable and comes with a short one (but not a wall plug so make sure you have one of those). It was also less than $11 delivered so not a lot to gamble on an occasional-use gadget.
Does it work? Absolutely, and a lot better than I ever thought it would. I was given a demonstration and in 10 seconds I saw a small cup of half and half turn into frothy foam. I'll admit, it does taste pretty good in coffee.
I 3D printed a stand to hold the mixer upright on the counter. Otherwise the base is too small and it tips over. That's not a complaint, just an observation. If you want it to stand upright, you'll have to do something similar. Otherwise, this thing is a good combination of simple, inexpensive, and effective.
