Automotive Relay Tester, Diagnostic, Test and Measurement Tools,Code Readers and Scan Tools,Test Relay Open and Close,with LED Light-Black and Red

Great little tool, very handy to check relays quickly.

Tested 4 relays 2 bad. Works as advertised

This thing is very impressive miss do a lot of electrical work on state vehicles and this thing helps out a lot. It works perfect.

I don't usually like to take out cords and alligator clips to bench test a relay. This is definitely a level up as far as convenience and efficiency to determine a functional relay. As for its longevity, that will be for another update. I've yet to come across a relay that is not compatible, again, that is for another update.

This devise is very accurate and easy to use.

Easy to use and quick nice to have in the tool box relays are something you check on all cars you work on

This small tool can save you a lot of time looking for a problem. It may not find your problem, but will let you know what is working so you can look elsewhere for your problem.

Easy to use. Great product for me with no experience
