I have this instrument stand holding 5 guitars and 2 bass guitars, and it is impressively compact. I would get a bigger one (9 instruments) if you have acoustics since they need more room.
I have had this for roughly a year now, and it still seems as good as new. The build is sturdy, and the rubber placement for the parts in which the instruments touch the stand is very good.
Only con I have seen is that the manual for assembling it is not very explanatory, but there are YouTube videos of other people doing it, so that can be helpful. Also, if you have your own set of screwdrivers, you should probably use them since the tools provided with it aren't really good.
