• I bought a couple of the really cheap digital calipers, always found the battery flat when I wanted to use it, or nearly dead so the display was too dim to read. Satisfying to know the $5 non-digital one I finally bought will work like new every time, forever. Would probably spring for a spendy name-brand digital if I used it frequently.

    Use the thumb screw to lock the slide when putting it away, otherwise every little movement turns the display on. In general, I suggest getting the ones which take a CR2032 rather than an LR44 precisely because the battery always runs out at in inopportune time and you can get CR2032 at the supermarket
