Review on WYNNsky Magnetic Thickness Woodworking Decoration by Marcus Merritt

I work with wood where sizes down to hundredths of an inch are acceptable. This is enough to adjust the height of the blade or bit. It probably won't do well for metalworking where you measure in thousandths. It's plastic so it can easily break if you drop it, but so can hundreds of dollar calipers. This all sounds negative, but I'm actually very glad I have this tool because it makes certain jobs much easier than with regular calipers.
