The hanger looks very nice when mounted with a guitar on it. Without the guitar it's not very decorative so consider how often you'll leave it empty.
The slanted position looks good and hides most of the black metal bar. I originally planned to put the guitar horizontally but this would expose too much of the black metal bar. Moreover, there was no good way to align my particular guitar in that position as the back holder would end up RIGHT on the jack port. Chose the slanted position instead and I'm happy with the result.
The guitar ends up between 7cm - 13cm away from the wall which is actually perfect since you can attach the strap easily to it while it's still hanging. I recommend a strap lock for that reason. While you could just leave the strap on the guitar, I find the look without it cleaner.
There is a little horizontal play in the hanger which comes from the adjustable base. It's stable though. The arms are also a bit wide for my RS 620 but I sometimes use this as a feature to hang the wound instrument cable off of it, too.
The screws that come with the set were annoyingly soft, to the point of being useless. My cordless power screwdriver stripped all three right away. Use some proper screws like Fischer and all will be good.
Note that the description mentions that this set is not suitable for nitro varnish finished guitars. Mine is a satin finish, I hope that will be alright.
