In general, it is a satisfactory purchase. It has a really large capacity but unfortunately it cannot withstand its capacity "weight". With full load (tripods, diffuser, studio flash, cables) and usage up to now 3 times, its plastics have already started to loosen, so I believe that soon the handle will come off. If you want to transport volume and not quantity, I highly recommend it!

It fits everything inside.

2 VL150 lights with cables and reflectors, 1 Witstro AD600pro, 1 Manfrotto tripod triman 028b, 1 Manfrotto monopod, 2 aluminum tripods for lights, umbrella for the flash, two 15-meter extension cords for the lights, 1 extension cord for the flash (and two girls as my wife says!!).
With all these and more, it not only closes tightly but also has extra space.

Besides the handle on top, it also has one at the bottom for carrying by two people.

It's incredible how much it can fit.
