Review on Uxcell Thickness Electronic Micrometer Measuring by Byron Forman

Yes, it's a cheap import with plastic parts, but electronics these days can often offer greater accuracy and consistency compared to mechanical versions. For the price this is a great item. I also went for the mechanical version and both agree. Given the low cost, I personally don't rely too much on machined (or stamped) parts. I can't say how long. Measure weight (thickness) if the skin is more than suitable.
