Many previous reviewers were right, the batteries do not last very long. We used this item several times a day and charged it only when is was almost discharged. It last just a few months. When it was new it worked great. We then went back to a standard frother using alkaline batteries. They only last a couple of weeks.Today after it had been sitting in my garage for a few months I was getting ready to throw it away when I decided to see if could be fixed, I do that to almost all things that break, I can't help myself, I am an engineer. Seeing no screws I resorted to brut force and grabbed it with both hands and tried to break it in two. To my amazement, it came apart and revealed two replaceable NiMH batteries. It snaps back togher also. It had AA 600mAh batteries inside. I ordered 4 POWEREX AA 2700mAH for $14 though Amazon. The higher capacity batteries should make it last much longer between charges.
