A DIY must have! ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️
Update Sep 2026: Finally I figured out how to retrieve live data for troubleshooting and was able to see exactly what was happening. I repaired the part and was back running again. I do wish that TopDon would provide more DIY training videos on the use of their products. That would help all of us who made this investment use their product more efficiently. But as far as the tool goes, it is very impressive once you know how to use it. Initially gave it: 10 Stars 🌟 ! Absolutely the Best for any DIY out there. It goes beyond expectations and simplicity is a must to have to get a professional opinion (or second) on any analysis. Don’t be left in the dark or get swindled by un-honest mechanics. Must have, easy to use, speed and features are excellent. UPDATE: By no doubt, this is one of the best systems out there to DIY mechanic's. With that being said, I only have two cars that I keep and the renewal cost of $495 after the first two years is disappointing. I was told that the renewal cost would not be needed to continue for the current cars that I have unless I get newer cars to my inventory.

Worth it.
I like it, BUT was it worthTHAT much? There is a learning curve, Chat GPT and Google seem to know more that any video on YouTube to do specific tasks. I guess it has saved me more in diagnostics than I paid for it so far. It has changed me from throwing a lot of parts at cars to actually finding out what broke also.....ok, buy one, it's worth it.

Decent scanner tool
This has allowed me to diagnose all my vehicles and has been great at doing so. The WiFi updates is very convenient. I don’t like the fact that I lose updates and support after 2 years though considering the price tag.
