I use Ride-on and I'm happy with it so far. Not sure if it's saved me from a flat or not as I haven't noticed. It also does the balancing of the tire as well.
My only concern is how much it would cost to install. My Ride-on is installed @ $15/ tire. I'm comfortable with that. If it was significantly more though, I would probably have to pass. I guess that depends on how often you change tires though.
