I've had this unit installed for about a year now.  It still looks good and was fairly easy to install.  I needed a couple of the rollers replaced and they sent me out a complete kit to replace them all.  The replacement parts looked better than the original.  I would suspect that they have upgraded those parts which is a plus for this unit.  I expect to have it in place for some time to come. I think anyone who buys this unit will be pleased with it
