"I originally purchased the cheaper 3 section ladder but a product recall meant that I had to upgrade to this version. So glad. This option has the spring arm controlled descent whilst the cheaper model drops out of the sky in a threatening lump. It has smoother linkages and a steel placement rod instead of the soft aluminium rod previously. This is a great ladder and the proof of the pudding is that my wife would not touch the earlier model but has no issues with this. Wy not 5 star all round? Well the spring arm must be mounted on the opposite side to the excellent grab rail but this obstructs both sides when sliding larger boxes uphill. And the descent is not quite evenly controlled as its a bit one-sided. However happy to recommend as a sturdy, high reach and high quality product."
