My husband is a pipe fitter and he always mentioned how he needed an advanced calculator and so I decided to buy him this and surprise him with it and he was so happy because he said it’s very useful and just what he was looking for! I also love how it comes with a case to protect the calculator! I just wish the price was a little bit lower because I saw at Lowe’s the same calculator for $39.99 and I wish I knew lol. Other then that, great:)

We ordered this calculator when the one that we had been using for the past ten years finally gave out. It is a good calculator, just wish it had some trigonometry functions built in.

arrived quickly. works great

I have an old model since 10 years and its dead now. Used it every day for my work. I bought a new one and still usefull. Dont buy the hard case that amazon suggest you, like I did, because you dont need it, there is a cover that come with that calculator.

Great item but I like the Construction Master IV better for my needs.

Perfect for carpentry

This thing saves me so much time when I am doing CA for projects at work. Easy to input values, easy to convert back and forth from decimal to fraction, etc.

It is a great calculate, and have a protective cover which is great. I am really pleased with it. John W.

I have always had one to work with makes life easy
