Pretty cool little tools that seem to be fair quality. This set covers the majority of automotive relays out there. I’ve only used one so far but it was a terrific alternative to swapping relays or using a short piece of wire. You can do your testing now with the key off, in most cases. Just flip the switch on the top of the dummy relay and let the diagnostics begin. I may have to buy an amp clamp that can do DC current to take full advantage of them.Very cool!I’m glad I found these.Update: had to buy a clamp that does DC just for these! Works :)

More times than I can count, I've had to make up a jumper wire to test components in my vehicles. Now with these relay shaped switches, that's a thing of the past. You get six of the most common relay types with a simple on/off switch on them to manually activate the circuit. It could not be easier.These could also be used in an emergency to get you vehicle home or to the service station. I won't be using them often, but when I need them, I'll be glad I have them.If you regularly do repairs on vehicles, then these are a must for your tool box.

for the diy mechanic.great troubleshooting tool to have.these relays only use two prongs.will turn on the device the original relay controls.the switch on top of these relays substitutes the control side of the original relay, which is the built in coil in the original relay.i used to manually using wires to do this previously, these relay testers make it quicker and easier to do.

Must have for trouble shooting on your own. Can save money verses going to the shop.

These are super handy to have, easy to use and really good quality. If you know about automotive, electrical and wiring you’ll understand how much easier these are to have than not have. Happy with these!
