I bought this for re-doing the plaster walls in my home--from 3' high down to the base board is now not a struggle, or knee torture. I am having to scrape the old paint off before I can spackle and re-paint, and this item has already made it easier, especially since I have like most of the interior walls to do. Assembly was easy, an allen wrench was provided, but I had to supply two 14mm wrenches. Be advised. A couple of adjustables would have also worked. Hardware seemed a cut above what would normally be supplied at this price. Only 3 stars for comfort, the padded part is really hard, but so what. At this price it is surprisingly well made, I looked at others more expensive and did not see the point in paying more, not for what I need. A professional mechanic would probably opt for a better unit.
