I decided to treat myself to some good digital callipers after my Aldi ones died.
Hoping that the new ones would not eat batteries, I plumped for a Mitutoyo 500-196-30 6"/150mm. It works well but is frustrating because every time I turn it on, it shows a number that came up when the battery was first installed new. (As per the instructions).
The second one I got was a Moore and Wright MW110-15DBL Basic Line 110-DBL Series. It uses a CR2032 battery instead of the usual SR44. I prefer it to the Mitutoyo, especially as it was about half the price.
I've had both for over a year and neither have had batteries replaced.
Both are accurate for my metal butchery, so it is down to personal preference, I guess.
