1) this holder is shorter than other models, so the back of the instrument may touch the support. (but for me it's perfect because I use it for a seagull merlin dulcimer, which is really flat).
2) also you can not turn the holder, you can fix it only to a vertical mic stand, impossible to fix to an horizontal support.
If those two point are not a problem for you then the holder might suit your needs because it's well build and easy to fix.
but I would only recommend it if the short arm is what you needn otherwise other holders are cheaper and with more possibilities
