This is by far the best Christmas ever. I'm an electrical engineering senior and like many engineers I love retro technology. My Santa knew exactly what to get me, and actually went above and beyond my expectations. I had the pleasure of unwrapping two gifts: a beautiful slide rule and a wonderful drafting ruler.

They are old-school calculators that engineers use for both problem solving and design. I am happy and satisfied with my first reddit exchange. I'd like to thank redditgifts for making this possible, but most importantly, I'd like to thank my Santa (who remains anonymous - I hope you're reading this darling!) for making this the best Christmas ever! <3
