Review on 🔗 Adjustable Crisscross Premium Bed Sheet Fasteners - 2 Pcs Fitted Sheet Band Straps Grippers Suspenders Corner Holder Elastic Heavy Duty for All Bedsheets, Fitted & Flat Sheets - Long Type (Black) by Rachael Staranowicz

The idea of this product is good and once installed it holds the sheet in place. However, it claims to fit all bed sizes, including the king, which I have, but it's too short for that. It stretches long enough for it to work, but installation is a real hassle. . When unstretched, the product is only about 40 inches long and the king-size mattress measures 110 inches diagonally. This means that after placing the fixing cross under the mattress, you have to lift the heavy mattress and crawl under it about a meter to reach one end. When you attach it, you're pulling it towards that corner, so now you have to reach down 5 feet or more from the opposite corner! And if the clasp jams and snaps to you, ay! That hurts. Good idea, but badly designed. And the other reviews are correct that the production is very weak, I can see it dissipating slightly after a few uses. I think a different four piece design, one for each corner, would work better.
