Easy to use and comfortable in the hand. Measurements are accurate. One important thing you need to know: the instructions say "Power: 3 V lithium coin". Not very informative. A part number would be nice. So I opened it up and the pill cell turned out to be CR2032. BUT there are also three LR44 batteries! I believe 2032 should run the meter electronics and 44 the LEDs (backlit display and Schrader valve lights).
