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!

Really nice set. Grind is fine and turn is easy. Highly recommend manual over battery operated ones.

Works good but have only tried it on fine setting.
Works good but should have an overall cap as seasoning gathers around the inside.
