My brother loved it!

I got this as a Christmas gift for my brother, who is an engineering student with a current internship. He absolutely loved it! He told someone else it was his favorite gift this year. He's excited to have so many tools and constants available in his pocket when he's at work or doing homework. Quality is great too--super durable and legible. I may have to order the Pocket Scientist for myself as a fieldwork tool.
