We love these. The quality is great. We were a little nervous about spending so much without seeing these but are very happy. It adds so much storage and looks great in our garage. We epoxied our garage floor before we put these in and it just looks great now. But the assembly- This takes awhile. We did it with two of us for the most part, working on different parts several nights. We did need our male neighbor to come help hang the uppers as it was too much weight for me. With the leveling and screwing extra hands were definitely helpful.
I would definitely purchase again- especially now that installing this with my spouse is a distant memory ha!
