Good Gift of Physics Students
We were looking for a gift for our very frugal Stanford Physics PhD student and this fit the bill perfectly. Small enough to fit in his wallet and something he seemed to get a kick out of.

Excellent Material and Great Design
I have used many of the Pocket X products (Chemist, Engineer, Physicist, and Paleontologist), and have always been thoroughly happy with the purchases. The material looks nice and packs in a lot of information in a credit card size. The stencils, holes, or many other features on the various products work well and make them very handy. If you see one that intrigues you, I recommend trying it out.
The Pocket Physicist has also been improved (in my opinion) by now using purely SI for Maxwell's equations on the front. The constants and equations on the back are easily legible and cover a good spectrum of physics.

Quality product, quality team.
I recently ordered the pocket engineer and pocket physicist. When they got delivered I was surprised to find that I had received two pocket engineers. I emailed the team at genius lab gear and they were super friendly explaining how they would get the order corrected for me. The correct order came within the next week. The quality of the product is amazing, and I highly recommend for anyone thinking about buying.
