Gibraltar product, so stability has never been an issue. Holds up well on the long run, against heat, cold, dust, etc. The Gibraltar stickers come of every once in a while, and this is annoying to me, but there is no perfect product. The turning point hardware is great, gives you a "levitating" feel for the cymbals. Also this moving base (moves up and down on a spring) helps you to protect your cymbals. Slight problem, the spring-base will not be consistent in every direction, so the angle of the cymbals will change slightly when the cymbal spins around. Still, I've changed every boom arms I have with these. And I have a lot. Is it cheap? No. Worth it? Absolutely.
