Bought two. The former is extremely inaccurate after several calibration attempts. The display of the second device stopped working an hour after opening the box. Having tried several brands of these "budget" gauges and all of them died within a month or didn't work at all, I'm sticking with the more expensive but reliable gauges from Hatch and Apera.
