It's so nice to have these for items that move around a lot. Great for rapid placement in tight spaces, and the air cushion is a great bonus that helps keep lights from dropping too fast due to lose knobs (accident).
I didn't mean to grab the 7' instead I was meaning to grab a second 9 foot. But I like these stands enough that I'll keep the 7' I have lots of use for these stands.
I don't really have any negative critique. If you need it for heavy equipment and modifiers get heavier duty stands. But I have used these for ad200's or led panels without issue.
