dunno about trs5000 but I got the mini bull for 50$ so I could sort my harvested transponders easier. Id be dissapointed if I wanted it for cloning. It can't do shit but read the chips lol. I doubt Id have much faith in the other cloners on ali. All the programmers are about the same functions so Id imagine the cloners are about the same as well.
The AD900 is only like 1500 to get started. Thats a cheap tool imo. If your in business and cant afford that your doing something wrong
