I'm trying to decide if its my Dh's impatients or what. It seems that when I'm paying attention to the sensor I can tell its dying a slow death.. sometimes I let it go, if its being consistent, but reading lower, then I'll leave it for a bit.. other times I'll just pull it.. But it seems that I go off to work and get a phone call from DH that states the sensor is dead.. nothing leading up to it, its just dead (by the way this happens on day 5/6/7 usually, so well over the 3 day usage.) Or he's out camping in the yard, when they left, the sensor was fine.. but by morning its dead and wasn't 'accurate' all night.. So, do you see both slow and quick deaths with your sensors, or do they typically always die the same way.. or is my Dh just really impatient and the moment he thinks its 'off' he pulls it.
