We use these for our home offices. While they are necessary to protect the rug it is also expected that you need to replace every 2 years becuase they do crack over time.
Once down and in position it works well at just lying there. Unrolling that prickly monster without inpaling your fingers is impossible. You must fetch the Blackberry pruning gloves and then have a go. GOOD LUCK
The product is fine for I need it for. I just wish it were cheaper. I can't believe a piece of plastic is over $20 and that there other ones there for over $50. That is rediculous.
