I received it today.

In terms of size, the 24L is intimidating, but in reality, it is VERY spacious in size.
However, due to its 25cm depth, it can fit more than you can imagine!

It fit (I'm not kidding):
2x Lumix G9 with 24-120 (12-60) lenses WITH extra 82mm square lens hoods
1x Lumix GX80 with Laowa 15mm (7.5mm)
1x Leica/Panasonic 85mm (42.5mm)
Cases, with batteries and cards.
1x projector
2x quad sets with AA and AAA batteries
3x Olympus recorders with lapel microphones in their pouches
1x Sennheiser Cinema boom with fur windshield and shock mount ("spider") + extra T shape hotshoe adaptor. We're talking about a 32-inch microphone without the XLR on top! It can even be used for self-defense...
1x case with small cables and audio adapters of all kinds + earbuds
1x Zoom H1
1x DJi Osmo pocket
1x DJI Mavic mini with its own case and combo extras
1x Viva mini POS
2x Power banks (large 20,000 mAh)
Every USB cable imaginable.
Emergency shirt, pen, insulation, screwdrivers, baby wipes, masks, blah blah blah...
All of this fits WITHOUT EXPANDING AT ALL!
On the outside, you can easily fit 2 tripods or one tripod and a large water bottle or even large lenses.

E X C E P T I O N A L!
I will definitely get another one for the rest of my cameras.

Update 25-09-2023:
2 years later, with daily rough use (throwing it around here and there due to haste) and it doesn't have a scratch! Anything else I've bought has broken within six months with such use.
I've changed cameras, changed microphones, even changed projectors, but the bag remains the same and looks brand new.
Everything still works perfectly, zippers, Velcro, elastic bands, everything, despite the conditions (from beach sand to hot rocks in Lindos).
It truly saved us this unbelievable summer, as it is also thermally insulated (oh yes...)
In the top compartment, I put 500ml water bottles and it keeps them frozen for at least 5 hours in the scorching heat of Rhodes!!!
Value for money from every aspect, get it while it's available.
