These work well.  I have been using one on my motorcycle for the last year. The display stops working when it gets wet, but after it drys out for a day or so, it works perfectly.  Would give it 5 stars if it had temperature in Fahrenheit. Have to use the conversion of double the C temp and add 30 to get approximate temp in Fahrenheit.
