Works great!
I bought this so I could bench test some headlight bulbs and it works perfect! I hate messing with any kind of wiring, but this is just what I needed. I don't know how much I will use it, but it's great to have it and not need it. Worth the purchase!

great tester
Works good with a battery on the bench or test on the car. Does what it said it would do. Handy test tool. No problem with shipping , came on time. Not a snap on tool but good for the money

You need one of these.
Get one of these. If youโve struggled using a multi meter for automotive diagnosing you will love this tool. I wish I had known about them years ago.

Great Tool to have!!
Built well, saves a ton of time looking for a bad cable/ground. Lights are bright and I am still figuring out how to work all the features so...if I am a beginner and it works great for me....I know it will work great for anyone.

Worth it
Pay for what you get! No breaker on the device. Small palm sized. Saves a ton of time. Iโve dropped it and used it in the field a lot, probably 20 days in the field and it still works fine aven though itโs been tossed into tools bags and had stuff piled up on it. Worth every penny
