I ordered this inexpensive volt tester to make sure my car jumper was working and high enough voltage. It just arrived and so easy. Although hubby had to tell me to connect the clip to negative cable, did that and then red positive and boom it tells you the voltage. So easy and convenient. One thing, no instructions whatsoever.

Now I'm an old school mechanic, and I love me a good test light with a old bulb in it and nothing else. But working with electronics and USB-C power delivery in particular has made me realize the need for a little finer details. Now I use a multimeter mostly but this is a nice blend of in between multimeter and old school test light. It's got the nice big handle and the probe needle if you can jam through a tire if you want to, in other words it's solid. But it adds the display with the voltage reading so you can be a little more accurate. It all works great, 4 Stars.
