Query: Great until it stopped working

I received this from my wife for Christmas along with an espresso pot. It worked amazingly to froth milk up for amazing at-home lattes and cappucinos. It was also great for mixing chocolate milk. It ran through its batteries pretty quickly but I attributed that to frequent use. It again quickly started to weaken so I changed the batteries a second time (in about 3 months)but this time the frother was no better. There was a small amount of corrosion at the base of the handle (despite always being place in the drying rack with the handle up). After that it basically just stopped working. I'm not sure if it was just mine, but I wouldn't necessarily get another one. I really miss it though so maybe...
