Good for testing electric components! Most of these are priced around 200$ Real good deal!

It is good product, i use it for PLC and also for car troubleshoot. Thanks

Very useful tool, all functions as described. Good value.

a must have product for any car electrical repair, makes it so easy

As a weekend DIYer, a tool where I can provide power and ground to diagnose electrical issues would be nice to have. I’ve searched and came across this tool from Allsun, the reviews I saw gave me the confidence to try it myself. The tool did its job and the money I would have spent to have a shop diagnose it, easily pays for itself. I’m glad there is a product in this price range for us DIYer and even entry technician that is on a budget. Looking forward to other products Allsun has to offer.

I just needed a tester for misc things. Works great
