Query: A must have for the home

I've moved alot of heavy stuff with these handy slides. The large (7" diameter) ones work best. I find myself not using the smaller ones much, not that theres anything wrong with them. I've purchased some off brand clones at the dollar store but they are not even close to the quality of the original moving men. I think it is obvious but these should only be used on carpet. If used on a hard surface the bottoms get scratched making them not slide as well. I think every home should have these.
