Band Industries Roadie 4 Tuner

They advertise this Roadie 4 as much improved versus Roadie 3, and the main differentiator a "something" that will come soon...the auto detect. How come to advertise something that doesn't exist?
It works acceptable for sequential tuning, but this is the same feature as Roadie 3 that is cheaper. The Metronome is useless. Wherever you put it in your pants' pocket or elsewhere, you don't feel well the vibration, and when you play the guitar the beeping is useless. The string winder is pretty ok, but you need to be careful to the speed with the wheel. I would prefer to wind the strings with an electric screwdriver. I put only 3 stars waiting for the "coming soon" feature. After that I will revisit my feedback.
