I have the snap on verus pro, the snap on ethos edge, Snap on modis, autel maxi sys pro, a cheap harbor freight $89 code reader and the bosch mastertech j2534 passthru. If i could start all over again i would probably ONLY have a few obd2 dongles that work with smart phones, a j2534 pass thru and a pico scope. 90% of the time obd2 dongles would be used, when i needed deeper capabilities the j2534 would come out and the customer would understand the NEED to pay more and in about 2% of the cases the pico comes out and the customer REALLY understands they need to pay more! Its been my experience with the big aftermarket scanners with updates and maintenance, well they just are not worth the investment.
