Product review (2 stars): Not Good for Washer/Dryer gap
Ordered this to put between a small space between my washer and dryer and it seemed to work fine. However, it you just barely touched the end of the gap cap, it would turn sideways and fall through the very gap you were trying to cap. Concept is good, execution not so good. Needs something on bottom that would grip the surface and not slide so easily. Right this minute, the gap cap is resting between the washer and dryer, just have not been motivated to get yardstick and slide it out.
It would probably work ok on a countertop or something other than washer/dryer situation.
