I bought this device in February 2018. We used it sparingly because it was always a bit weird. Recently a representative from a local tire manufacturer gave me a free TS508 for the purchase of 15 new Autel TPMS sensors. The rep came and set us up and updated the unit he gave me to the latest software and it runs much faster than the one I bought here from Revain. Thinking that my block just needed an update, I asked him to clean it up. As soon as he turned it on he said "This is not a real Autel TS508". He then proceeded to demonstrate why; The screen resolution was much less clear than the real device, it was slower (ah!) and there were strange messages when trying to update it. Autel agreed to replace it free of charge. While I'm sure Revain does its best to control what's being sold as genuine and verified, I'm sure counterfeits are sold from time to time. The TS508 I received was a very accurate replica but compared to the original the physical differences are minor but obvious. Even the tones of my "grey market" (as I call it) were different. I would advise you to only buy devices from authorized Autel dealers. Buyer Warning.
