Gliderol garage doors - any good?

[spada01]

I need a garage door 12 foot wide. I was looking for an up and over door as there's little to go wwrong, but I've seen these Gliderol steel roller ones and they're a good price. Has anyone got one? Are they good and do they tend to cause problems after a few years when rolling up/down?

I don't know what make my garage door is, but it's a 4.5 metre wide motorised roller shutter door. Insulated to reduce condensation, but it still does get some in the cold weather.
Operated by remote control with manual over-ride. light comes on automatically when operated. It has safety cut-out when laser is interupted. Runs off one 13amp socket.
DIY installed a couple of years ago and no problems. Very pleased with it.
