I have never bought something like this before. I always buy those honey-comb-vinyl-thingies you see at discount stores. I have a lot of children (eight!) and with our wood flooring, the rug "pads" under our wool rugs would always get kicked up underneath and create bumps/tripping hazards on the top of our rugs--annoying! I was able to buy my new wool rugs for such a good price here on Overstock, I thought I'd give these a try. They seemed to be a decent price for the declared quality. Anyway, we are very pleased with them. I really love high-pile rugs, but they are so pricey. These rug pads help mimic the effect of a super-high pile wool rug. Plus they keep the rug from scooting around--another problem with lots of foot traffic indoors. My husband--not a rug aficionado by any stretch--liked them so much he wants me to buy one for the wool rug in our bedroom. Yes, sir!
