Review: 3+ years later, and still going strong! - Im currently on year 3+ with this digital temp gauge and have zero issues to report. It is supposed to be good for 5 years with the battery that comes in it. I have to note that the battery in this temp gauge can NOT be changed. Still a good purchase for peace of mind on my modded 2 stroke scooter.
Review: Must have! - Must have temp gauge for moped tuning. Very easy to use and program!
