In this pricerange I think you cannot find a more reliable holder. This is the only one I use, I have 8 guitars and they are all hanging on the wall in my studio. This holder grips the guitar tight and securely. I have never had any misshap or problem with these. They also look very good and professional. And if someone was to bump the guitar or hit it from below, the grip on these holders is constructed in a way that keeps the guitar safe and firmly in its grip. I advice you to buy these and not go for the cheaper models that don't have the secure gripping construction, especially if you have children in your household.
It's a simple addition to any Guitarist/bassist life. I have had no problems with it thus far so I can't really see many issues other than the material feels a bit cheap meaning that at some point sooner or later, it wouldn't surprise me if it broke but that's just my paranoia about my instruments getting damaged. But as I said, no problems so far.
