Bought this to make some space on my desk. It's really lightweight and stable, but I like the fact I can move it around on wheels when I feel the need to. Keeps my setup very mobile. I have a hard floor though, this might be different on carpets.
Just make sure you roll it carefully, because this version's legs (on wheels) go straight down instead of at an angle. So the center of mass might catch you by surprise and your setup might tip over if you're over enthusiastic. Just something to keep in mind, it's still quite sturdy.
Also, the space underneath fits your legs nicely, so you can play keyboard/synth with a sustain pedal sitting down with no problems. The top layer is also nice for standing while playing. And the 3 layers are height adjustable as well.
