The media could not be loaded. Extremely easy to read having large digital display. When lucky enough to get a good one, they are accurate within about one-to-two hundredths of a volt — as measured with my $500 Fluke ET-88 multimeter. Comes with adhesive mounting tape. Has 3-foot wire leads appearing to be about 22-26 AWG gauge wire. With small gap in housing where wires exit the plastic housing, a dab of silicone gel should seal it to becoming waterproof. One downside is there is no ON-OFF switch, but perhaps unnecessary since another Reviewer on Amazon noted the amount of the slight draw when connected constantly. However, the 2nd digital display meter was not as accurate as the first one; see attached pic. I ranked this a 4-star because of the 2nd display not being accurate enough —- close but not as accurate as the first one. They come two display meters to a package..I have included pics and video to demonstrate my claims in this review. I highly recommend this product, even if you have to return-and-reorder until you get two good ones. However, I have had this product only a few days, so I cannot attest to its longevity yet. I'll update this review if the product later fails in some way in future.

Easy to read display. Works great for vintage cars with 6 volt systems.

grat good price

They aren't accurate but it's a good indicator of what voltage range you're in.

Very economical voltage meter
