Review on DigiPas DWL80PRO: Compact Digital Level & Angle Gauge - Accurate Protractor, Bevel Gauge, and Angle Finder, 0.05° Sensitivity, 4 inch Pocket Size by Kyle Cross

Having never owned a digital level I hadn't realized before I bought it how difficult it would be to read the display. The numbers themselves are easy to read, but the indicator of a positive or negative number is almost impossible to see even with reading glasses. So I have to adjust the level up and down a few times and watch the numbers to see when they crossed zero to see if I'm looking at a positive or negative number. However, it works great.
