Ben 10 Cartoon

anyone's kiddos watching this? My son is obsessed with and is constantly taking my old watch and turning into one of the ten aliens and wanting to play the Ben 10 game on Cartoon Networks site. Its actually a decent cartoon, its about a 10 yr old boy that finds this watch and it lets him turn into different kinds of aliens and he uses his powers when hes an alien to go good deeds but it also shows the mischievious side of a 10 yr old boy. Also I'm looking for merch from the toon if anyone knows of any, I found the watch (Omninitrix or something) on a site but it says its not coming out til next Nov.

Edit: My sons name is no longer Gavin, he even told the receptionist today at the Dr.s Office he was Ben and stuck with it, hes Ben all day, hes totally obsessed, I TiVo all the episodes for him and he tries to make me play them for him all day, hes getting as bad as me too and makes me fast forward the commercials.
