I've had the V1s for a while and the V2s are just as good if not better. The shells feel firmer, the corners are sharper and thus fit better in backpacks atop of better internal space, the added grab handles are better, the flush lid is much nicer and makes accessing stuff inside easier, the materials and new dividers are SO much better, alone there worth the upgrade, and you always end up with extras to use later! These are easy to stack up in a closet or under your desk and just keeps everything neat up in one place or in a few cubes, you can see the pictures just HOW much stuff you can shove into these and still keep them fairly compact altogether in a closet, and I always keep one of them in my 45L travel backpack, easy setup and so dang modular.
These cubes are just fantastic, the new versions are much nicer with sharper corners, meaning more internal volume, however I did notice their vertical space is a bit shorter, you could get away with more verticality on the V1s due to the design of the lip and zipper side flaps, but now that they're flush with the lid you lose some of that, but you also gain more corner space and the internal materials used plus new dividers are WAY better. Lose some win some! I use these as at-home organizers for all of my camera gear, on top of having one of them in my 45L travel backpack, modulated to individual trip needs. Needless to say I love these, they're so easy to stack and organize together in a closet on top of their travel utilities.
SMedium: I was able to pack my Sony a7cr with cage, Sigma 17mm f/4, Tamron 20-40mm f/2.8, Tamron 70-180mm f/2.8 with battery pack and a sleeve of filters into this thing. The Cube fits into my Osprey 34L snuggly, but it works. It's also nice to be able to throw a PD leash on it and use it more as a bag than a cube if need be. The dividers don't fit the gear I have as well as I'd like, hence the 4 stars.
