Customers say
Customers find the electrical tester works well, with one mentioning it’s effective for diagnosing auto electrical faults, and they appreciate its quality and value for money. The device is easy to use, with one customer noting it’s particularly handy for testing relays and solenoids, and the cable length receives positive feedback. However, durability is a concern as multiple customers report it breaking within days of use, and customers disagree on the clarity of the instructions.
