Review title: Maverick: short-lived
Product review: Purchased the Maverick Laser Surface Thermometer to chart water temperatures for a residential "pump and dump" Water Furnace heat pump. It worked fine for about five months, then started showing obviously erroneous readings. Changed to new batteries, but no improvement. This gadget has never been dropped, exposed to extreme temperatures, or abused in any way. The 90-day warranty is past, so no help there.
