4 Stars
Very accurate, ruggedly built, waterproof, but not bright enough to read in sunlight
My only disappointment here is that the display completely washes out in sunlight.I installed it on a motorcycle, so sunlight is unavoidable. I need to cup my hand over it to read it in sunlight, not the best maneuver when you are riding a motorcycle. :-)I really appreciate the reading is done in hundredths of a volt--it provides a much more detailed view of the charging system and the effect of various loads on the system than with a voltmeter that only show tenths.It would be 5 stars for a motorcycle if the display were bright enough to be visible in sunlight. It probably is bright enough to be visible inside a car or a boat (it was designed for a boat).The attached photo is from inside the garage, and the display is good.

5.0 out of 5 stars Solid product, well made. Perfect for motorcycle.
Reviewed in the United States on March 1, 2017
This is a great functioning little voltmeter. It was important that I used a voltmeter with a display that is easily viewable in direct sunlight. Although a tad pricey compared to other meters of the same purpose this is a quality little piece. I installed this on my motorcycle with a switch as an option to turn it off when parked. Looks great and easy to read in direct light and very bright at night.
