Nice Frother
Color: Black
Just what I wanted. This frother is powerful and all I need is the low setting for frothing milk. I’ve also found the stand works great for the frother and 2 of the e attachments. I’ve only had it about a week and haven’t had to charge it. I highly recommend this frother.

Best rechargeable handheld frother.
Color: Black
I am so happy that I found and purchased this hand held frother. I've bought others; battery operated, rechargeable, corded and this is the best by far. It came fully charged from the manufacturer, I use it every day in the morning and haven't had to charge it yet! So reliable! It does a great job mixing quickly, frothing, or a quick remix. Such a great price too.. This baby is a keeper 😁

Great addition to the Kitchen - Not just for coffee!
Color: Black
works great for my morning coffee and can also make whip cream for those special treats!!! Cleans up easily. The recharging and attachment holder is great so you are not hunting for the attachment you need for the job. This has been a great product and completes the task at hand very well. It has the 3 power selections for different jobs. The attachment and the base are built well and very stable. I would order again (if need be) and I would also give a gift!

Powerful vortex of blending…
Color: Black
Too powerful!! I use a handheld frother for mixing coffee/lattes, and when my last one died, I read extensive reviews to find a new one. I liked that this one had a stand, and three speed settings seemed like plenty; unfortunately, this frother is unusable even at the lowest speed for mugs that are more than 50% full, my goodness - it created a coffee vortex with walls so high it looked like a massacre within seconds. We’re absolutely keeping it, now my husband can make whipped cream in seconds, but now I’m shopping for a weaker version, and we’ll be a two-frother household.
