This is a great stand. I often play cavaquinho (a brazilian kind of ukulele) on gigs, and it is always tricky to leave the cavaquinho somewhere while I play other instruments, as the instrument is small and doesn't fit to guitar stands. This stand solved my problems. I now use it in every gig, usually attach it to microphone stands, it is very stable and holds the instrument well.
Another great thing is that it allows you to flip the clamp and put it on horizontal bars also, so I have also used it as an add on to multi instrument stands to add the cavaquinho to it. perfect! highly recommended (I will actually order a couple more for my bandmates as they were also very impressed with the stand).
