Good day! 
I`m owner of a car tuning company and when I needed to get the diagnostics tool, I have purchased UNISCAN 3 . I have research automobile diagnostics market and have understood, that UNISCAN 3 costs cheaper than any analog. 
I was surprized with the enormous list maked cars that this device can make  and also a set of functions and operations which it can  made. 
I`m  use this device more than 3 months already and for this time UNISCAN have never brought me. 
I was able to connect and diagnose all cars Peugeot, Polonez, Porsche, Proton,  Renault which visited my service. 
I am assured  that I has made  correct choice in favour of UNISCAN 3.
