Don’t bother
It’s glitchy and won’t read the the rpm with any accuracy, the function button doesn’t work. This is a waste of money.

Partial malfunction, seller quickly replaced!
*Update* After sending the seller an email I received a great reply. They will replace my unit even though I missed the return deadline by a couple days. Damn it's nice too work with good people. *Original post* After 3 hours of use the first digit on the LCD screen stopped working. The unit was easy enough to program and has all the features I was looking for but I must return it. This was mounted on a portable generator and has not been exposed to inclement weather.
