I purchased the rack as a more compact replacement for the individual stands I'd be using to hold my guitars. I bought two extra expansion holders, which were easy to add to the rack. It comfortably holds 3 electric guitars, 1 electric bass and 2 acoustic guitars, with enough headroom to potentially fit up to 2 more electrics (or one acoustic). It's very modular and yhe instruments are held in place at an angle, which makes it very hard for them to fall off, even more so with the moveable foam rings on the bottom bar that secure the body in place. Though my guitars are fairly standard shaped, so I can't say for certain if it would be a good fit for explorers, flying v's, etc. The only feature 'missing' (but not really, as I have not found a rack that has it) is optional security straps on the neck holder, like those on many guitar stands. But, even without those, I still feel safe placing my guitars on the rack, even with cats running around.
