Looks interesting.As I don`t have an iphone,I`ll stick with my full size reader.
One thing mine does is to id the car it`s plugged into ie,vin code.
My brother-in-law borrowed it a couple of weeks ago when he went to look at a Polo.When he plugged the code reader in & pressed the id button,it came up with a different one as to the vin plate on the car.He didn`t say anything to the seller,but when he got home he rang the Police & told them.Turned out the car was a clone,so I think the code reader car id function is probably it`s best feature.
