Review on ZLKSKER Stainless Calipers: Accurate Parallel Crossed Measurements by Ted Slaughter

I was a bit skeptical about purchasing this product but it turned out to be the best $20 I've ever spent on a gauge. Very useful for finishing, I don't know how I lived without this tool but it is very useful and I am very satisfied. Pros: Works fine, product quality is good, hardened pen is really sharp so no issues so far. Slightly scratched on aluminum. The look and feel of a quality product. It's good to have both scales. Cons: Scale markings could be better, with bold lines or letters representing inches/half/quarters of an inch. I get confused and have to check with a different ruler each time until there are no more errors. It would be very helpful if the lines were bold for an inch/half/quarter of an inch.
