The gf has a pair of raiden machine bindings she's giving me for xmas she doesn't think I know about. I have zero concern about their durability; why, because raiden/nitro has been doing it right for a long time and they stand behind their products. Does history mean shit can't happen, nope and that's why I have back up bindings and a warranty.
Just took my Machines out for a rip last weekend - very impressed with their performance so far, I'm sure you'll enjoy! They seem very well built and I have zero concerns about the airbags popping. They're in a thick casing that short of sticking a nail into it isn't likely to break.
