Effetto Mariposa Tyreinvader for XC

Anyone using these? Forum search didn’t return any hits. They look lightweight and simple, two qualities I value highly. Other Effetto Mariposa products get good reviews for quality. Looking at using them on 29" XC bike, Racing Ralph/Ray 2.25" tires with Snakeskin sidewalls. Appreciate anyone’s shared experience, good or bad.

Thanks!
