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!
