Awwww I see Max
I misunderstood, sorry. I use the word 'cool' a whole lot when describing the Buzz too LOL. We were the opposite, I got the Buzz first and hubby who has never had much interest in any mod at all was suddenly very interested. One day with his Buzz and he packed up the Tornado he was using and said "sell it". He still has a Lazer mod he carries around, but that's it. I'm the mod hound of the family 
I think most people would prefer a knob of some kind and I agree it would make it more user friendly. However I'm a freak and like having to use a screwdriver to change it. Not only am I ditzy, I'm a tad clumsy too. I would probably knock a knob right off or accidentally be changing the voltage every time I handled it. The way it is now is much safer for me to use. At one point Mike was talking about having it an option to have a knob or the screw turn, but hadn't found a knob he liked yet. So maybe you will be able to add that on later.
