Absolutely garbage, I can't figure out why they keep pumping these out. I started with their liquid filled gauges, all 4 of which leaked, and lost calibration within 2 days, all of which I returned under warranty. Now this gauge, is quite accurate.The issue falls, with it now sitting at 5in/g with the car off. Yes, it can be recalibrated, no, I shouldn't have to do that every time I drive to the store. If you're selling cheap gauges, sell them cheap!
