When you buy a helmet, you want a good fit. You go to the store, try all brands and models, until you find the good fit. Then you want safety. A strong shell, good padding, good foam layer. Then you want the right type (full face or other) and a good visor. Skully offered one model only. Statistically, one model only fits a minority of people. They had one choice of materials, type of helmet, visor. That limits the number of potential customers to only a few.
I looked at them, and decided the helmet wasn't safe enough for me, and probably wouldn't fit.
What they could have done instead is produce visors and build-in electronics for a range of well known helmet models. That way, I would have bought a Skully set for my preferred helmet.
