Love it!
Color: C-Black, Size: Model C Rechargeable
Love mine! No more batteries. I make at least two cups a day and froth my creamer. Love the fact I don’t have to recharge very often.

This is a great daily user.
Color: Stand Black 1, Size: Battery
The battery life has been wonderful. It is very easy to use. The stand with the frother is very useful. It keeps the counter clean and is easy to grab for use. I use it in many liquid items and it stirs very well. I think the price is good. I would definitely recommend this frother.
