    They need to do a better job with batteries!!

    They need to do a better job with batteries!!
    I read the other reviews stating the included batteries didn't last long but that wasn't an issue to me, easy to put new batteries in. So, if the batteries didn't last long, or maybe were even dead on arrival, I wouldn't have worried too much about that as long as the gauge worked well. What I didn't expect though, and didn't like, is that mine not only had dead batteries, they were already leaking and corroded like crazy!! If I hadn't needed the gauge right away I would have returned it! I had to dig the old batteries out then clean the battery compartment and install new batteries before I could even use the gauge at all.After installing the new batteries it seems to work well. I can't speak to the accuracy because I don't have another gauge to compare it to. And even when I have had more than one gauge that differ in readings, how does one know which one is accurate, or more accurate?
