I've got one and love it. We don't take it off though. Oliver couldn't reach it and when he could we dropped the base of the cot. We did cut the strap off though, because it didn't matter how tight I pulled it it still hung into the cot and I thought that was dangerous (and I never, ever did it up to change him anyway). It'll probably have to come off after the next growth spurt, but we will lay it on the single bed in his room then. We live in a unit with no space for a real change table so its an excellent use of space. I use a towel that matches his cot linen to cover the matt so it looks nice too.
