I like this ruler, very handy to have a reality check when designing PCB's on that big monitor with zoomed in PCB. Only remark is the breakoff tabs on the top of the ruler, they are a bit sharp and rough. Otherwise the ruler is very nice.

Thanks for your review. About the edge, it depends on how the PCB has been split from the panelized board. In case of sharp edge, you can easily smooth it with a small piece of sand paper.
I had a shipping problem where the product didn't arrive, but Tindie helped me with a solution.
Owner is very communicative, would recommend because he is helpful.

Hi Robert, Yes I apologized and I asked you to wait until 5th February to see if you receive it, because I have no more information than you about your order (there is no shipping tracking). Please note that I am not responsible of postal services delay and lost. But I always try to find a solution when this kind of problem happen.
The ruler has an amazingly useful assortment of information in such a small item. Possibly it could be bigger as the text is smallish, but small size is also an advantage - it can carried easily in a wallet or pocket. Very good value for money. Wasn't sure how to rate documentation - there isn't any...
This PCB ruler does its job quite well. It is well designed, silkscreen is clear and not too thin. PCB is thick enough and the overall format is not too big (8cm long) and would easily fit in a pocket or a small toolbox but having it longer would be interesting for me, maybe 12 or 15cm . i have one at each place I may need it. that is worst its price. May buy some again.
The next version should be about 15-20 cm full scaled ruler. Pleas make better position for the break cut oft the pcb. In this version the break is bad positioned becouse it's on the rule line und I get no straight line. Every time I draw it it is wiggled.
