Thanks to it's bulletproof ruggedness and heavy-duty components it's incredibly stable. Whether you're mounting heavy moving-heads directly or via a truss system you have the confidence it will not fall over - not even if an audience member lightly bumps against it.
Unfortunately, the best part about the stand is also it's greatest weakness. The stand has already claimed multiple "victims" from toes to floors. If you're not careful while handling it will break something, but definitely not itself. I've managed to make a considerable dent on a concrete floor with this stand, and the stand didn't suffer at all.
Stableness comes at a price, and that price is weight. If it were, say, 5-6 kg lighter while still as stable I'd rate it a solid 5 stars. For what you're paying you're getting a very solid and dependable stand, but bear in mind it's not what I'd call fun to move around. Still, I propably wouldn't change it for anything else. I'd definitely consider having a smaller, lighter version of it for less intense gigs if there were one, but I would still keep the heavier "big brother" around for when it's needed.
