Its more influence of nostalgia than any product review.
I do not even remember the purchase date of this tool, 2011 or 2010.
I got this SHWD KYS0411 from eBay with out carton box.
Today I did some web search and found few interesting pictures about it (carton box & PCB).
I am not using frequently this tool, and this explain of why it has survive that long.
But when ever I need it it does the job.
