This thing is great! It’s nice and sturdy, well made, and being in forensic engineering means always having an awesome product available and small enough to go anywhere! But certainly doesn’t skimp on usefulness. Definitely gonna recommend to more people. Awesome idea and product.

A textbook in your pocket
My brother is in the middle of a college degree in engineering and asked for a "cool ruler" for Christmas. I got him the Pocket Engineer and he said it was his favorite gift this year! He loves that he can take it to class and to his internship and have so much info on hand. It's sturdy and well-made and the printing is very clear!

Small but mighty
I bought 2 of these for high school graduates getting ready to enter college in engineering. Even though I bought these as little bonus gifts to the main presents, the students were most excited about these!
