versaboxen: i love them. great planetary gearboxes. totally worth the money.
hex shaft, sprockets and other related hardware: haven't had a problem. like the tooth count on the sprockets only thing i don't like is the black shaft hides sharpie marks...
verawheels: i don't know what my team did wrong but our versa wheels lasted about an hour of practice driving and 10 matches before they were balded and had to be replaced.
