    Works but a possible battery drainer
  

*by A***E on Reviewed in the United States on November 17, 2019*

Pros:Easy install, wire is flat so you can hide it fairly easy.Easy to set upCons:For some reason mine likes to stay on (light up display) for hours (and possibly days) after I shut the car off^due to bad door open/close door sensor?*After two days voltage got down to 11.6~*There is a "shut off at X voltage" setting which I'm gonna set to a high 11~12. Hoping it won't drain my battery again.Pretty sure the MPG is way off. I set the engine size and seems to be 10~ MPH off./update it was what was draining my battery and fixing the door sensor didn't stop it. If you car sets more then two~ days stay away from this. The  "shut off at X voltage" setting even on the lowest voltage will drain your battery.
