I used these to replace a very old disgusting rug on a front porch. The look is very attractive and I'm very pleased. I am a 68 year old female and laid the majority of them by myself without any issues. However, broke my ankle the day I was going to complete, so probably won't finish until spring. I live in a cold climate, and any painted surface becomes very slippery with snow/ice - I think these will be a big improvement as far as a security issue walking on even in the winter time.
