I'm not confident this replacement frother is going to last. When I first received it I put batteries in it and it just started running without even pushing the button... very strange. I wiggled it in the air and it would stop then start up again. It was randomly running on its own without pushing the button, I had to consistently wiggle it in the air for it to stop.

By day two, it was working as expected, however the power is definitely not what the original one was like. I'll wait and see how quickly the batteries run out and make a decision on a replacement.
