Negative Positive
Title: started off well, didn't last long
Review: read good reviews before purchased this - but had to soon buy another due to it not having a back light so you can read temperature at night. it doesn't sound an issue, but 70 percent of the time i use it at night! it gradually got less and less reliable - the button kept sticking down so i couldn't release it .... overall it worked well in the light the first 6 months.
Is the review positive or negative?
