Worked great until my year was up and was subscription with a subscription renewal. ### 1/5 — Broke my car *2026-06-29, version 3.2.9* Cost my hundreds to fix ### 1/5 — Mini *2026-05-31, version 3.2.9* Сканер работает, но не формирует отчеты. Техподдержка пропала, перестала отвечать. ### 1/5 — Do not recommend *2026-05-09, version 3.2.9* Used to be fast and handy tool but now, freezing firmware unable to fix and doing diagnostic over 1.5hr still loading. Do not recommend!!! Uninstalling and destroying device ### 1/5 — Disappointed *2026-04-10, version 3.2.9* I’m sure it’s great for some things but not for modern Isuzu’s. I bought this specifically for a 2024 dmax. It doesn’t support it, so I paid $99 for the Thailand Isuzu update and still no joy. I feel like they robbed me. Buyer beware ### 1/5 — Waste of money *2026-03-26, version 3.2.9* Do not purchase this has been a complete waste of money and time, can never reset oil lights even with FCA purchased can hardly even clear codes and attempted with multiple vehicles ### 1/5 — Jeep or dodge or Chrysler *2026-03-24, version 3.2.9* Won’t load my auto authority account ### 1/5 — Think diag *2026-03-14, version 3.2.8* Absolutely scammers don’t waste your money. Very disappointed ### 1/5 — Not all cars are supported *2026-03-05, version 3.2.8* Unable to access Mitsubishi outlander with All Systems Diagnosis. It might work with older cars. ### 1/5 — Used to work *2026-03-05, version 3.2.8* I have a small obd dongle for a few years, it did what I needed, but recently it stopped working, as in I wanted to get my car to force a regeneration. Up till recently it had done this and I renewed my subscription. But recently it has changed, the subscription that you buy no Longer works! It allows you to buy subscription. But nothing happens! When I go to use the subscription content it just says purchase again!! I logged a complaint with Paypal.
