Best frother ever!
Color: Flat Black
Super easy to use! Love the 3 speed mode. Makes my morning coffee a breeze to make. Also love the fact that it’s rechargeable. So far only charged once and it’s long lasting. Favor part about it is the storage, doesn’t need to stand straight and be out. Can be easily cleaned and stored away with the cover. Feels very high quality. Highly recommend!

Works Great So Far
Color: Flat Black
I've only used this item for one week. But it is working great. I primarily bought it to use when mixing protein powder, and it has performed great. The only concern that I might share is that it is made fairly lightweight, and I wonder how long it will last. But can, up to this point, recommend it.

Powerful!
Color: Lux Galaxy, Size: Rechargeable Z1 Motor Max
This thing is powerful and works great! I was hesitant about some of the negative reviews, but this is worth it so far. I use it every day and haven't charged it in the week that I've had it. Some people complained about turning it off.... It's not that hard. Just hold the button down for a second or two and it shuts off, no fuss. If you tap/press the button you'll cycle through the next speed and then off. I only use the first speed to make my protein shake and matcha. I feel like the high speed would just whip everything to pure foam! I'm hoping this lasts me a long time.
