Turbo decoder Ganzua HU100 V.2 Generation - Fits Saab, Buick, Holden, Vauxhall/Opel, Saturn, Chevrolet, Cadillac

Totally the useless ,watched all the videos on how to use but still no good ,took it to my friend who is a locksmith for 31 years in his words “it’s rubbish “ ,this tool is for the hu100 locks so comes with a blank hu100 tester key which doesn’t even fit into a hu100 lock ,the pins on the tool just go up and down where as they are surpassed to go up and stay there ,contacted the seller and all I got was ,you need experience to use this tool ,what more than 31 years ?,my friend has his own tool and works perfect , stay well clear people and I’m not happy with amazon for supporting this kind of cowboy , just to add , this item is described as a turbo decoder , turbo decoder is an actual brand and this is NOT one of their products steer well clear of this company ,just one more thing , the company that sold this item was Collaradiestramientobarato , watch out for anything being sold by them
