The build is tough enough for daily shop use, the 5m cable reaches every corner of the vehicle, and the overload protection keeps me from damaging sensitive electronics. For professionals who need speed and precision, this tool pays for itself.

I bought the V200 to fix a persistent issue with my truck’s trailer light wiring, and it worked like a charm. It quickly pinpointed a voltage problem in the wiring that was causing the lights to flicker, and I fixed it in 15 minutes—no more guessing or trial-and-error. Even as someone with limited electrical knowledge, I found it easy to use: the clear indicators show exactly what’s wrong, and it’s simple to move between testing different circuits.

As a mechanic and DIY auto lover who values precision, the Circuit Tester V210 has quickly become my go-to. It’s packed with features and built to handle the demands of any garage or job site. The clear LED display instantly shows voltage, circuit continuity, and wiring faults—making diagnostics thorough and way faster.It automatically detects open circuits, short circuits, and other common electrical issues in vehicles.
