I liked the first one so much, I got a second one for my other instruments.
They're easy to use, fold up compactly, and work neatly both for guitars and for basses.
The grips adapt well to asymmetric headstocks. They look like they _could_ bump a tuning-peg if you hung a guitar on them carelessly, but it keeps not happening, so I stopped worrying about that.
I'm chronically clumsy, and still haven't managed to knock one of these over, whether they're empty or are holding one or two instruments. It's even easy to carry these up and down stairs with a couple of instruments hanging from them.
I've only used them at home so far, but I wouldn't hesitate to take them to a gig.
I find it even easier to grab a guitar from this, than from a regular stand, so they're actually encouraging me to practice more.
