It's difficult to install. As in several days of swearing, a visit to a hardware shop for some NON-locking nuts and attacking it with a hacksaw because I don't have my roof rails 2 feet above my car - like most people. Now it's finally in place it's just fine. It is a perfect present for the DIY-er of your house after they have left their wet towel on the floor and used up all the loo roll. If you're going to be putting it up yourself, think seriously about how good you are at constructing these things - you might want to spend a bit more money on a better thought-out design.
