Product review (2 stars): Not good for washer/dryer space
I think they'd work much better in a kitchen between countertops.  The info says it can be used between washer and dryer, and that's what I needed....but it doesn't stay put (I have about 1.5" of space between), and every time I open the detergent drawer it falls away.  So I don't think this is a very good application for this to use for washer and dryer.
