I use this with an NS Design WAV4, with a DIY endpin.
The design is excellent, and it's easy to use, even if it soaks up a lot of floor space. As another reviewer said, think PA stand rather than guitar stand. And it's made by K&M, so it has that reassuring feeling that it'll outlast you.
I've had exactly one scary moment with it, when I didn't clamp it properly, and the top part rotated and allowed my bass to fall sideways. After catching the instrument, I screwed it in properly and that's never happened again. Entirely user error, but a gotcha worth knowing about.
The fork is large, to accommodate all sorts of bass necks, but this is a feature. Because it has a relatively narrow neck, I can practically let my bass fall in the general direction of the stand and know that the stand will catch it.
I only knocked one star off the handling because it's necessarily big, which means it's awkward to move around once it's set up.
