Query: this doesn't work - don't bother with it

I bought this thermometer recently. It doesn't show above 68 (even when in the 80s) and below 60. Have tried everything and nothing gets it to show correct temperature. Also, difficult to read. 3 times bigger than my little thermometer of >20 years that broke and yet harder to read. Cost more to buy a padded envelope to return it than the cost of the thermometer (it came in an envelope not a box). Also, as per other reviews the screw that come with it to hang it up is too big - after all this time you think they'd fix that problem also. Not worth the money - not worth being given free (in my opinion). It just doesn't work.
