I purchased the Top lift for my 2015 Jeep Wrangler (4 door) and put it together in 2 hrs. The lift works great and I can now remove the hard top myself in less than 15 minutes. This includes removing the 8 screws that fasten the hard top to my Jeep. With the hardtop stored on the TopLift unit, I can pull Jeep into my garage with the same space that the Jeep took up prior. I was missing two screws and called them on it. They were very spontaneous to answer and said they would send out immediately however I went to local hardware store and purchased as I wanted to get the unit installed that day. I do recommend watching the video on installation as the user guide that came with it was outdated. Well worth the money and I usually never do reviews however I'm very delighted with the quality and ease of operation
