"This door opener was a breeze to fit for me apart from one issue. There is little flexibility of the height for fixing the main header above the garage door, and for me, I had a 7mm steel lintle which I had to drill through to get a fixing (took ages). Apart from this, the fitting is much easier than the instructions initially look, and the door works really quietly and well. For me, the pack contained more accessories than I needed (i.e. external keypad entry system, and manual overide for powercut from the outside). But would I reccommend this, absolutley. It works a dream and really is quiet. Remotes have a fantastic range (tested at about 50m), and has now aided my grandmother on opening her garage door."
