Great product for PCB Designers
For Open Source PCB Ruler
The product is very good and and very useful to compare different sizing of different components. You will have visual representation of the size rather than what you see in computer screen. It is very beneficial.
Pros
very fine printing
great quality
appropriate size
cons
front and back rulers are not matching although they are dimensionally correct.
some what pricy. ( i am Indian)
the area with lots of smd pad at back size may be useless
overall 4.5/5
keep it up hemal

Thank you Dhaval for your review. I've ran out of stock, I sent the last PCB to you. Before I get the next batch manufactured I'll make following changes in design. Scale on just one side, reduce the number of smd pads at the back, add some more footprints and try to find a cheaper manufacturer to reduce the cost.
Thank you again, Good Day!
