Works well. Keeps my guitars within reach, while at the same time saving space and keeping them safe. No chance of flipping over or anything like that. I was suspicious at first at the lower "self-balancing" arm, which holds the weight of the guitar. It's not that it's flimsy or weak, it's just a little unnerving as the arm can swivel freely along it's axis, until you put the guitar on it, and rest it against the neck support. Then the weight of the instrument keeps the arm balanced in the right position.
The 3 stars for quality: right after assembly (which took all of 3 minutes), one of the neck lock springs just came loose and it was a fairly difficult to put it back to where it needs to be (involving pliers and screwdriver for leverage etc). I noticed there's really not much holding it in place. It's just a spring with a curved end that rests against the metal arm, on both sides. It's not tucked in a little hole or anything like that, so I could see how that can happen. A lot of potential to improve on the design here.
That said, once the spring was back in place, it didn't came off again. It's been a month now and I'm fairly happy with this holder. I have 2 strat style guitars and a smaller acoustic (gs-travel) on it.
