Pros: Reasonable accuracy, and detect small temp difference created by different colors absorbing more or less heat. Small size makes it easy to carry around. Handy for hobby uses. Easy to use, just press the button.

Cons: Once you set time the unit never turns off! Remove battery and replace to reset. Unit gets less accurate as min and max limits are approached. LCD setup text very small and difficult to read.

Overall Review: The instructions are confusing in regards to the clock display. They should say that setting the clock causes an always-on mode, rather than indicate a settable parameter. Handy for checking battery temp in rechargable toys or tools.
