I've been using MagMods for a couple of month now, and I'm very happy with them. Great quality, easy of use, extremely fast gel/grid changing. MagGel works great for bare flash, but with diffusers may not work (though they are expected to come out with their own bouncer). Also, I like keeping the MagDrop on the flash at all time, but that sometimes means making some extra room in my gear bag.
