The Fowler caliper battery cover broke shortly after getting it, I replaced it and it broke again. It now will intermittently change the 0 point, so I need to check the 0 point every time I use it. Buttons become a bit dodgy after awhile. I subsequently purchased an Igaging Absolute caliper, it has been very reliable and accurate. It was less expensive then my Fowler Euro-cal and is built much nicer. Purchased several things made by SPI, they either broke or was so far out of spec when I received it that they were returned. Been using Compac and Interapid indicators, they work flawlessly for years and I like that they go more than 1 revolution for the scale and are +/- indicating (go in both directions, Revolution Counter, Constant Measuring Rotation). I use Starrett 0.0001" and 0.0005" dial gauges, but there are many other great brands (not made in China) out there. The indicators and dial gauges where purchased as new or new other at about 1/2 the usual outlet prices. Enco with their 20% off is another consideration.
