Review on OIFIO Protector Anti Scratch Deterrent Protection by Sheila Hill

I've bought these a few times and they've always worked great and stayed on my couch for weeks to months and my cat wouldn't scratch them. We bought a new couch and I wanted to put them on it so my cat wouldn't have to scratch them but they aren't sticking to her.... I thought it was the couch stuff but I still have the previous sofa so damn I put it on the old sofa to see and they don't stay on the sofa. Part pops out and then sticks to itself. Not sure if the glue they use on it has changed, but if one sheet would last a month of my cat constantly leaning, touching, or trying to scratch it. until less than 24 hours I can no longer recommend this brand and unfortunately will not buy it again.
