I loaned My og buzz to my GD and she lost it. I like them best out of all of them. I think the controllers were better than the PWM the pros have. If I find another one and I have the do-re-mi I'm buying it. Like I said I still got my beta buzz. a Buzz Pro, a regular Infinity, a beta Infinity Pro, and an Infinity Pro retail Oh and a partridge in a pear tree.
