Title: Not built to last, not even built to use
Review: We only need a very simple device to take simple read of temperature. This one seems like a good option, price is just right and has all the function we need. The first day I got it, did a simple test, boiling water read out at 100C/212F(~), which seems just right. And the next a few days, most of the time it functioned as supposed to, however, I can tell the error increased. Yesterday, about 1 week from the 1st use, we calibrated again using boiling water, the readout was 110 C/2xx F. Something was wrong, but still it was close. And today, it just became ridiculous, the room temperature water measured at 81 C/ 180 F. It just not getting better.
