I don't usually buy things in anger. But for about the 25th time this year, I pulled my cheap chinese *splat* 12" calipers out, and they had eaten yet another battery. I decided long ago not to buy anything but good quality measurement tools. This chinese caliper is from before I learned that lesson.
This one is coming.

It is NOT a Chinese knockoff. It is genuine Mitutoyo. It will need a battery every 5 or 10 years, NOT every single week!
I might glue one of these to the back of the chinese caliper and relegate it to the garage...
...where hopefully I'll forget about it laying on the floor and drive a bulldozer or something suitable over it.
Or I might just exercise one of the anvils, and smash it with a hammer. Smashing with a hammer would be good therapy!
