I bought this for my specific use case which is a small closet that has high ceilings. I had the Rev a shelf unit and in the lowered position it came out too far from the wall. The ability to offset this one at an angle in it's raised position means the lift can be attached to the sides of the closet at the back wall. That means when lowered, the leading edge of the clothes come about 38" from the back wall as compared to about 50" or more with the Rev a shelf.The lift hardware also seems to be superior to the Rev a shelf. It handles more weight smoothly. There's a soft lowering at the bottom and enough power to lift a significant amount of weight once you get it going. The Rev a shelf only had a cheap bumper at the bottom and it felt like it was going to break when lifting about 60% of the weight that the other unit had no trouble with. Total weight I put on this was 6 two piece suits with heavy duty cedar suit hangers and about 15 sweaters on wooden hangers.Only issue I had was It arrived with a broken piece (the plastic shield that keeps dust and dirt out of the action). I contacted the seller and they promptly sent me a replacement and it was very simple to fix.
