I have several of these. They are like reading glasses, they are everywhere. More accurate than el-cheapo dial guages and better than other digitals I had tested, small, durable, easy to read and use, good for glove box or shop or anywhere.
I don't know why the previous reviewer hand to remove the rubber handle. I just rec'd mine it it requires one screw to change the batteries. Mine works flawlessly, even in bright light. Wah Wah, if the battery doesn't last forever, geeze get a grip! My guess is that those who are having trouble are probably experiencing an ID 10 T error!
