I have had this product for about 2 years and I have loved it. My husband is a below the knee amputee, and so he slides more than not when getting into and out of the bed, as well as tosses and turns, and slips while sitting at the side of the bed getting his leg on, I have had major issues keeping fitted sheets on the bed. They pull from the corners as well as the other side of the bed, frustrating for me cause I like my sheets straight and smooth.I tried other products, that just didn't work, clips snap off and other brands that go under mattress just too hard to lift my king mattress to get to. This band is easy to install, I do it myself, and as I change my sheets/bedding weekly, very convenient. I remove it completely when changing my bed and put back on, only way to have hospital corners. Over time I found the band has stretch out some, which is to be expected, hello its a rubber band even small paper bands do the same. I found using the strap designed for adjustable beds to work. I stretch and tighten the band on 3 sides and use the strap at the end of the bed to hold it tight. I do need something for sides, again husband slides off side of bed when getting out.It does make small indent in corners of mattress when tight but not an issue, who sleeps on the corners? For price vs quality I give 10 stars, I would rather buy a new one every couple of years vs paying funeral costs due to how frustrating it is remaking the bed due to my husband. This product has held up and made my life so much easier, I wrap over mattress pad, fitted and flat sheet, during winter I have an additional blanket, keeps all snug, and doesn't pull out of bottom of bed even when my husband gets them wrapped around himself.I would recommend to anyone who has issues with keeping sheets on the bed, this is great for people like me who is or has someone that has a harder time getting into and out of bed, does more sliding then hopping into/out of bed. It's not often I submit reviews for products, unless I'm very disappointed in it, and if I could give 10 stars I would.
