Const. Master 5 is the greatest calculator in the world. It takes so much of the work out of my job and it's so easy to use. The yellow color makes it really easy to find too.

I have used your calculator for years, 15 years to be exact and I have been very satisfied. I owned your Construction Master IV calculator and it preformed every calc to the letter. I will never use another brand but your. You have met my expectations and I'm very happy with your product. Great Job and keep up the good work.

The thing I find annoying is having to hit Conv, M+ when I want to subtract something from memory. It's an extra step compared to the old Pocket Handyman II. Other than that, I think it's pretty good.

No more rafter square and tables for me - Just cut em by the numbers. I never stack a roof without this tool. Precutting the hip is a breeze...
