Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator for Contractors, Estimators, Builders, Framers, Remodelers, Renovators and Carpenters

My husband was impressed with this product. The cover was a nice added feature.

Works as expected

Arrived late but excellent product.

My only criticism is with the plumb and cheek calculations for rafters. The plumb cut is given the same as the pitch when of course it should be 90 degrees less the pitch - eg. a 20 degree pitch would give a plumb cut of 70 degrees. The construction master would give the plumb cut as 20 degrees the same as the pitch angle. Also the cheek cuts for the hip and jack rafters are always given as 45 degrees which is correct for the plan view on the horizontal plane but not the actual cut.

Only lasted a year

My son-in-law, a contractor, thinks its great.

Our second one and it works great!

Perfect

This is a great calculator for anyone in any type of construction field. I highly recommend this product to anyone.

works great for a time. After a few weeks of use the screen turned dark. I have recently bought another. Wonder how long the screen is going to stay bright
