Randal: I'm an automotive and disel mechanic and I wish I would have bought this type of volt tester year's the screen is easy to read and saves a lot of time finding the problem compared just a light bulb probe.

Willitever-stopraining: Excellent piece of kit & it saves having to dig out the multi-meter for simple quick tasks

S1eaperr: So my Mac tools version like this one pooched the other day, and to my surprise, they couldn't implement a fuse in there somewhere. The Mac guy doesn't come often enough to the shop to justify sending it to Mac, waiting for it to be replaced, all the while I can't diagnose anything without this thing anymore. Plus I'm pretty sure the warranty just ended, of course lol. So I was looking for a replacement of the same caliber, and found this one. It's basically the exact same thing, just the clamp is a little different, but way cheaper.

Pros: The voltage display seems to be accurate, it really helps to diagnose, especially when a light bulb can't really tell you accurately how much voltage is there, and then have to bring out the volt-meter. It's doesn't feel cheap, and the black rubber piece on the rod is nice as to not ground somewhere you don't want to. It doesn't do reverse polarity, so your ground, HAS to be on ground.

Cons: The spring cord is nice, if you want to test close to a ground, but if you have to go even a bit far, I find myself having to un-coil the cord alot.
The clamp is somewhat strong at clamping, but it does do the job, if...

R. Payne: What a nice tool that makes circuit testing a quick and easy process! The flexible cord makes for effortless use. One stays in my toolbox at all times.

SJ: So took a chance on this because the snap on version of this is around $90, works good to a 10th of a volt, reads the same as my snap on multi-meter. Backlight is nice for working under a dash or low light. Only four stars because on the display the numbers kinda disappear if not looking at the right angle, can make it difficult to read in tight spaces. As others have said the rubber over the clamp is stiff, but I just slid it up the wire past the clamp since it is just a ground and doesn't need covered.

D A M: Nice tool for quick read on DC voltage. Like the fact that it reads 3v - 48v ! When i really looked at it, noticed that the wire was just crimped onto
clamp. Pulled out the soldering iron & made a more positive connection, but that's my own preference. The boot that covers the clamp is a little stiff,
but no big deal. Clamp looks like it is cooper plated, the wire is not cooper. Over all it's great for getting a read on power to fog lights, radar detector
radios, tail lights, fuses, ECT...
