I think that for the experience, guys are gonna be willing to dish out the money for this. Look at cam sites, guys will sit at home and spend $2-$4 per minute to watch a girl strip for them and here it's .50-$1 to have a device rub your cock the right way

Plus this device is beautiful because you can just set it on your cock and it'll do the rest, the lazy way to jerk off, ha ha.
I do think there's gonna be a lot of people that are gonna buy it and then realize how expensive it is to actually use and probably put in the closet and never use it again, but I'm sure many people will be dishing out the cash for more minutes if it does deliver on the feelings it can give.
