I've been using mine for about 2 years now, I gig atleast once a week, up to 3. I'm playing bar gigs with drunk girls jumping up on stage hanging on me and my keyboards.
I do have to say, one time a girl was so drunk she basically leaned all her body weight on one side of my keyboard which sew sawed the other up, then it came down but off the stopper, I luckly stopped it with my foot before it hit the ground.
I love a heavy duty X stand or Z stand because of the lack of bounce, but set up and looks, the Spider wins hands down
