Full disclosure: I haven't used the item on my mailbox yet, so I can't speak to durability. I took off one star because all of my lights are "warm white", not the "cool white" with the blueish tint and these seem to lean cool. I was disappointed because the picture shows warm white lights. However, it looks like it'll be a nice addition to the mailbox and I love that I can get light to the box without having to run a long extension cord out.
