I really like the Vapor and fresh battery aspect of the T-Rex but am starting to worry that it's about to become extinct due to the Charging and Fragility issues. It looks as though the Maxx is the T-Rex in wolf's clothing...My guy at Rebel is gonna get a Riva for me to try...It seems like everyone likes it and has the good aspects of the Dino w/o having to worry about glue and charging issues. Are there any Riva users that are having any issues or is it as good as sounds?
