I’ve tried multiple non slip items for under rugs, my dog runs about 100 miles an hour across my door Matt’s and hallway runners and nothing would hold my rugs in place I would be moving them back in place 10-15 times a Day was more than annoying I found these after multiple other non slip devices failed and they work amazingly!!! Occasionally they come loose but that’s my dogs fault he only has 1 speed, FAST. So maybe once or twice a month I have to set the rugs back and then they’re good to go. I do clean under the pads every week or so to keep dog hair and debris off of them and that helps them stick better and last longer. For anyone with a dog that goes hyper speed these are a must for rugs on hardwood
