Product was easy to order. Followed the stair measurement instructions per the website and the lifts fit well. Installed them myself (reasonable handyman skills with an adequate set of tools). The instructions included were very lacking as is mentioned many times in these reviews. I was able to use online videos to help figure out how to complete the installation. One note, the instructions state that you need a minimum of 2.5" space from the wall. At 2.5", the back of the chair rests against the wall and would rub as it transits. I mounted mine 4.0" from the wall and have about. 5" clearance when the chair is occupied and transiting. This is due to the small amount of flex in the back of the chair when occupied. Frustrating install, but very sturdy. The pricing is lower than comparable units from other vendors. Overall very pleased with this stairlift.
