I can't believe all the good reviews! out of the box it didn't even work! There was even a sticker on the back saying QC passed. I do not think so. I thought maybe the battery was dead so I replaced it but it still didn't work. What happened is, no matter how I move the angle, it never goes above 0.6 degrees when reading. it is not helpful. Like I said I'll go to HD to buy a real one that works.
