I needed a single case large enough to carry (6) Godox/Flashpoint AD600s with batteries, chargers, AC adaptors, cords, and other accessories to and from my studio. I was tired of lugging 2-3 different bags and occasionally having things go missing or forgotten as they were spread over different bags. This case solved it all. It is heavy duty, great rollers, and lots of space. I was able to get all my AD600 lighting kit in this bag. It is extremely heavy with all that gear, but I only have to lift it in and out of the car. Otherwise rolls so easily and makes my kit much more accessible. I liked it so much I bought a Medium Case for my AD1200 packs and now have both kits perfectly organized and ready to go. Strobepro continues to impress with their design, their quality, amazing prices and listening to customer feedback. I only wish this bag was an inch taller to make packing the AD600's with the battery pack attached a little less snug when standing vertically. But it works and I love it!
