Feature:
Excellent quality, workmanship and materials. The other brands have not stood up to these hangars in my experience.

Quality:
I have used other hangers in the past, that have marred the headstock of my guitars over time, but these have not altered the finish in the eight years that they have been in use. Also, with other hangars, if the neck of your guitar was wide (I.E., a 12 string) or narrow (I.E., banjo or mountain dulcimer) you can use a little strenth and pull apart, or squeeze together the arms to the desired width without too much effect of the overall strenth of these hangars, but don't try that with most other brands, as the yoke will usually break.

Value:
I have used other hangers in the past (some coting over $25) which have not met the quality of these.

Desirability:
A great way to hang all your axes for protection and display.

Ease of Use:
It cannot get much easier than this.

Support:
I would give them a 10, but I have not had to deal with the company directly. With other hangars I have had to, with little success. Some marred the finish of my guitars and some have had cheap welds on the yoke.

Overall:
I have heard owners in the past complain about marring the backs of their acoustic guitars or the wall when using these hangars, but if you take a block of wood with a thickness that is best determined by the thickness of the guitar, and mount it to the wall behind the guitar hangar, you alleviate this problem. I personally use a router to make a nice edge of the exposed surface, then stain and finish the block to match the backplate of the hangar.
