Used it once then left in the garage and the temp was below freezing for several nights. The next time I used it in a few weeks, the batteries were dead. I changed the batteries and it has been working fine for a few months now. The magnets work well for in-car use, and the screen flips right side up no matter which way you orient it. Accuracy and response seem crisp. I wish it had a backlit screen because I have to use a flashlight when it's in the shade. The contrast is not strong. But I have no regrets and the price is right.
