I have been using Jobber Calculators for over 30 years. I believe I'm on my third one. I have had this Jobber 6 since 2004. Besides changing out the batteries, the only thing that I've had to replace was the keyboard numbers and I did that last year. Highly recommend this calculator if you are in the engineering or construction field. I have been using this calculator in piping design and I would not have any other calculator. Many coworkers use the jobber as well.
