From Spencer Boerup (creator) and the MagMod Kickstarter Page:
MagMod is the simplest, easiest, strongest, and fastest speedlite modifier system for Canon + Nikon hot-shoe flashes, period.
Over the past 8 years of my photographic career I’ve seen my share of bulky, awkward, and cheap flash modifiers. Each has their own unique problems and flaws.
None of this is an exaggeration, and if you're a working photographer you're probably nodding your head because you've experienced this too!
Don’t you think it’s time we have something better?
That's why I decided to make the best flash modifier system ever, and this is MagMod.
MagMod is a magical flash modifier system that frees your speedlite flashes from velcro, straps, and adhesives by geniously incorporating the invisible powers of magnetism. Each modifier is a single molded piece of high-quality silicone rubber that is sleek, compact, easy to use, and dead simple.
