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!

Customers praised this wallet-sized ruler with conversion references as "excellent" for engineering students and professionals. Reviewers highlighted "high quality" construction, sturdy metal design, and comprehensive reference data including formulas and conversions. Some noted items arrived bent in envelopes. Minor concerns about information organization and international shipping costs.

As a high school teacher of more than 30 years, I can attest for the declining state of penmanship and general use of writing implements. If this generation has any hope of drawing legible, usable, dare I say, "beautiful" organic structures then that 'hope' lies with the incredibly useful "Pocket Chemist" tool/template. I buy a class set every year for my small group of chemistry nerds and send them off to college fully prepared to not embarrass themselves in organic chemistry. This product is just that good! So divert some of that science budget away from Elephant's toothpaste and spend it on something with staying power like the Chemist Stencil.

My son who is in studying Engineering really liked it. Great tool!
