I own several of these for my notro-finish electric, acoustics, classical and bass guitars.
The cork looks make them to fit in the living room (they don't stand out, which is a good thing), I had zero issues with my nitro-finished neck guitars, they can hold full scale basses with no issues and all in all they do the job perfectly.
Just, keep in mind that the wall screws are not included. The installation is easy if you know how to operate a drill (no complaints here).
The price is a little bit salty compared to the black ones but that's the only downside, still, condsider the purchase an investment.
The mechanism that secures the instruments is fairly straight forward and any accidents should be a rare occasion and definitely a user error (has never happened to me, I don't expect to happen to you either).
So, in conclusion, if you need wall stands for your instruments, you find the black ones kinda "dissonant" and on top of that you own nitro-finished neck guitars, then these are for you.
