Very nice!
Very nice tester. The ability to apply power and/or ground to whatever you are testing is great. That feature makes quick work out of testing relays, bulbs, motors. Especially useful when testing power windows.It is a little bigger than it's competition, the power probe, but significantly cheaper. I recommend having two of these. That makes some diagnosis even quicker.I am pulling one star because the power/ground cable does not have a strain relief and will bend quite a bit where it enters the tester. Over time that will cause cable breakage.By the way, the "touch metal" is for turning on the tip illumination. Touch the short ground lead to it and the illumination comes on. Another handy feature.

This made troubleshooting a car restoration much easier
The car i was working on had its harness removed when i got it so I needed to literally hook every thing back together including reparing several broke wires, connectors, and shorts.I thought this was cheap enough to get but wasnt sure it would be used more than my multimeter. It made testing so much easier. knowing wether something was hot or not and able to inject power into a circuit to make sure the load was connected properly made this job so much simpler.The cable is long enough i could crawl underneath the vehicle. and its never got disconnected from the battery no mater how much wiggling around I did. The tip could scrape through corrosion to make a solid connection and if I put power into the wrong circuit, it has a audible alert and circuit breaker that would reset after a few seconds. It could power any load on the vehicle even the starter for a the few moments i needed to verify it.Great product. Have no real criticism. possibly wish it had a audible tone when probing.

Great value for a DIYer
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.

Cable is made of a stiff wiring and makes it a pain to use
But it functions well and is a great value. I am going to use the cable off my broken power probe.
