Highly recommended, except for large bodied acoustics.

I've got several of these and use them on everything from a ukulele to a 5-string jazzbass. It works great with all kinds of headstocks (it adjusts itself for offset headstocks like Fender).

I believe this is the exact same product as a slightly more expensive K&M branded model. It certainly looks exactly the same and the build quality seems very good.

The only problem is with acoustic/semi-acoustic instruments with thick, full sized bodies. This wall mount does not provide enough distance from the wall to allow such instruments to hang freely. The body will lean against the wall which may not be ideal. Thinline acoustics will be fine though.

Except for this I can see no problems whatsoever with this wall mount. Excellent value for money, highly recommended!
