What real users say
Master Automotive Technician • April 26, 2026
I own an Autel MS909 and a ThinkScan 689BT. The 689BT does 95% of what the Autel does at a third of the price, and the lifetime updates mean I never get hit with renewal fees. It's in my service truck daily.
DIY Car Enthusiast • March 18, 2026
The ThinkDiag 2 dongle replaced a $50/month subscription scanner app for me. Bidirectional control on my Honda from my phone is incredible. ABS bleeding worked first try.
Independent Shop Owner • February 12, 2026
Solid mid-tier diagnostic tool. Some advanced module coding on Mercedes is locked, but 95% of the work I do — Hondas, Toyotas, Fords — is fully covered. The free updates seal the deal vs Snap-On.

Does THINKCAR support CAN-FD and DoIP?+

Should I choose a tablet or Bluetooth dongle?+
Tablets (ThinkScan series) suit shops and daily users who want a dedicated screen and faster sessions. Dongles (ThinkDiag) suit portability — keep one in your glove box and diagnose from your phone via the app.
Can THINKCAR scanners do ECU coding?+
Yes — flagship models like the ThinkScan 689BT and ThinkDiag 2 support ECU coding and module programming for select makes. Coding depth varies by vehicle brand; check the supported vehicle list before purchase.
Is THINKCAR better than Autel?+
