I have now had this for 2 1/2 years and it has held up well, performed as well as I could hope, protected my instruments and displayed them nicely. I have found no others which worked as well. There has been risk of my instruments falling or being knocked over. Neither are they likely to touch or scratch one another. I have a collection of solid-body, semi-hollow and acoustic guitars with always at least three in the rack at a time.
I did opt for the wheels, which makes it that much more convenient to roll the guitars out, when I am playing with others, trying things out on more than one instrument at a time. Likewise, it simplifies rolling them out of harm's way, when grandchildren or others are at risk of damaging them.
