Query: Cheap crappy product that doesn't work!

I recieved my frother and it doesn't work, it rattles and I can't even figure out how to open it to change the batterys. I have owned a boujour brand in the past which worked great till it was accidently dropped on the floor. Even broken I was able to duct tape the last one I had and it would work half the time.
