Everything is great about this frother except that I always have flat milk foam because there is no notification that it is done!  It just turns off. No beep. Not even a flashing light. 

I guess I'm meant to sit here and watch the foam build. I'm not impressed. Every morning I screw my coffee up. Honestly it would probably be a 5 star product if it had some way to let me know it was done frothing the milk.
