Does the job!
Every now and then, I have questions about blown fuses. While I have fuse testers, I found I had no EASY way to test relays. Feels lightweight but solid, easy to operate, accurate and quickly identifies bad relays. Good value for the money. Don't throw this thing around, although it's durable, it's still made out of plastic. Does the job!

Works good
Does not work on wide spade relays but you can get frustrated like me and make it work

This thing works. It's worth the price.
This is a solid product. I had an intermittent AC issue on a 2007 kia. It was mimicking a bad high speed fan, ac blowing cold driving and hot when at a stop light. Was about to purchase a fan because of the symptoms. Ordered this instead and checked the relay. This relay was clicking but this tester definitely said it was bad. Ironically sometimes this would say it was good and sometimes it would say it's bad. Just because a relay clicks doesn't mean the relay is good. This was a solid purchase that helps you diagnose the relay.

It's a cool tool but really when relays and such don't work it's more that they sick after someone uses and this thing doesn't test out very well so basically I'll get a false reading every time
