Great frother!
I love this brother and recommend it if you are looking. I love the way it sits on the charger and you don't have to worry about charging it or a battery. I only use it for my coffee so the one button is all I need.

The stand isn’t worth it
Love this device, the stand is frustrating. Falls apart easily and is very easy to bump/fall apart. I have not tried the wall option for stand, tho it’s nice that it is a back up option. Overall the mixing device works great- I use it with powders so far.

Disappointed After on durability
Dsappointed After a Short Time. At first, this product worked great, and I was really happy with it. However, after just two months, it completely stopped working. Very disappointed in the durability. I expected it to last much longer.

No battery replacement
The frother is more powerful than my last one, and has an easy recharge usb connection! I add cocoa powder and cinnamon to my morning coffee along with half n half. Using the frother mixes all the ingredients and puts a nice foamy topping!

The Best
Love this product! It holds a charge for weeks without losing force. I've purchased several of these type products in the past, but yours one, by far, it's the best. Love it!
