Product review (1 stars): Be prepared to glue the magnet to it. It doesn't stay put.
The magnet does not stay stuck to the backside, so it's constantly falling off our dishwasher. I'll probably end up supergluing it to fix it, but that's not the point. It should work, as is. And it doesn't. Rather annoying to have to go out of my way to make it functional just to be able to use it.
