I really like all the extra storage this 4' x 8' overhead storage provides. The materials are very sturdy, the powder coatings are all well done, no sharp or jagged edges anywhere. The installation instructions were clear, with one minor annoyance regarding which way the mounting bars should be situated when screwing into the ceiling rafters. Early in the instructions, they show mounting with the large oval holes up, then later in the instructions it looks like the oval holes should have been on the side. I mounted with the large oval holes up, thinking that would make it easier to get stud center on both sides. This restricted me when mounting the vertical bars, which need to be perfectly straight down, since I could only move from one hole to another, not slide within a hole. It didn't cause a problem though, all the vertical bars look straight. All in all, I really like this product and recommend it to others.BTW - The biggest problem I had when installing was trying to locate stud centers. My stud finder didn't leave me confident that it was finding stud center and I wanted to be absolutely sure I got that right, I didn't want this thing falling on my car later. I then stumbled on a YouTube video that showed the guy using the stud finder to get close, then poking a nail through repeatedly to find the two sides of a stud. I balked at this at first, not wanting to poke holes in my garage ceiling, but then realized, who cares about a few tiny holes, the important thing is to get the lag bolts installed into the stud center. I then used the smallest drill bit I had and a drill to do the same thing as with a nail. I would use the stud finder to mark what I thought was both sides of a stud, then drill through the drywall and poke with the drill bit. It I hit wood, I would move a little further out and repeat. Once I had both edges identified, I then knew for sure where stud center was located. The stud finder itself was good at finding a stud, but terrible at locating the two sides. Once I adopted this process, things went very quickly. Of course, I wouldn't want to do this inside my house, but for the garage, this process worked great.
