Disappointed
For The Ultimate PCB ruler
First off, these cannot be used as a straight-edge, they used perforated tabs on both sides of the rule, one one of the ones I got, they didn't even bother to break off the tabs. Second, one while side is text, which I suppose I should have seen before I bought it. So nothing on the obverse side that couldn't be put on a PFD or paper 'cheat-sheet'. The text on the back is so small I need a magnifying glass to read it, which means to use that info the required magnifying glass size has to be considered as part of the overhead to use it, another reason the info is better off on a piece of paper.
The footprints etc. are good, but not enough of them, it would have been better to use both sides for those.
The Adafruit one overall is much better, but this one gives me some metric info the adafruit one does not.
