Love these roll holders. They look stylish, modern and do their job.  The only thing I was slightly disappointed with is they could only go one way - i.e. I had to have them "open side" pointing towards the toilet.  I like to have the part anchored to the wall closest to the toilet in case the little lip which stops the roll falling off isn't that effective.  That said, we've hung them, and the little lip appears to be doing its job.  No rolls have escaped as yet!
