The screen is so weak that we can not see the LCD numbers.  I mean, we have to literally hold it at the right angle / light to see the temps and other values.  PIECE OF JUNK...we used a similar version in our RV previously but after 10 YEARS it stopped working.  This one, same brand, doesn't work well to begin with.
