Beto pressure gauge presumably continues to be the best in the market. It is sold under different brand names that includes Oxford and Panasonic. I managed to buy a few of them for $9 each or so, when a store was depleting their merchandise. Meiser relies on fragile mechanics subject to deterioration, due to dust, humidity and corrosion. At some point its reading begin to be off and you do not when and by how much. Even when new it will not work at low pressures that may be needed in winter. I have Meiser gauges - just do not use them . Besides validity of the reading, the issues concerning gauges include: amount of air released during the measurement, ability to access the vent, ability to use the gauge in the dark, secondary functions such as bleeding air. People may also want to use the gauge with different vent types and switch units. How long the battery lasts with digital gauges? In Beto it seems to last forever and it generally tops the field no matter what criteria you consider.
