Title: Drain battery even you are not using it
Review: This digital tire gauge drains battery even if you are not using it.I checked my tires once a month, but, I already have to change battery about once per year.The gauge still use power to memoris the pre-setting of tire pressure. come to think about it, thepre-set memory is useless if you have 2 different cars. (Because it only can memoris one front and one back tire setting). The 2032 lithiumX2 battery is not cheap, I expect it should last at least 5 years.
Is the review positive or negative?
