My sister in Phoenix gave me a jade roller two years ago and I barely touched it. It just sat in my drawer. Then I visited her last summer, and my skin felt so tight and thirsty from the dry heat. She made me use it with a hyaluronic acid serum every night. After three days, my skin actually felt plump and calm for the first time all trip. I had to eat my words and start using mine back home.

My buddy used the thinner stuff for his garden shed floor and it sagged after one winter. He ended up having to rip it all out and put down 3/4 inch anyway. The extra cost up front would have saved him a ton of work and new materials.

My $2000 rig gets outshone by a phone camera on a tripod... it's a special kind of humble pie.
