I have been using my inchmate calculator for 10 years extensivly in my job as a mechanical designer. It is a great calculator and very fast. It helps me in adding and subtracting dimensions for layout of construction documents. The one I have does not have the rise, run, and slope features but square and square root keys acheive the same results just a little slower. The only improvement that the manufacturer could enhance for this calculator is the incorporation of sine, cosine, and tangent keys for trigonometric calculations. These features would win a five plus star rating for this already great calculator.

How many times does it take to calculate where it make that CUT on the most expensive piece of wood in your collection? Exactly once! For years I have performed double, triple and sometimes many more checks on calculations for cuts on expensive, rare woods. The Sonin calculator has made calculation time short and accurate.

Easy to use and right on everytime. Now if I just get a tape measure that tells me when I measured wrong, I'm set!

I don't know about you but I have a tough time adding dimensions after a few hors on the job. This tool will save time and money and get you home a little sooner to your family!

I am a 35 year experienced builder and have owned both the Construction Master and Sonin Calculators. I liked the Sonin better because it's easier to use and more suited for problem solve a builder experiences. But I have noticed some people having problems when the Sonin displays the memory error message, they think it broke because they can't get it to escape from that. All you have to do is press the clear button twice or 2 times then turn it off and back on, or just use a pen and press reset on the back of the calculator. It tells you how to do that in the instruction booklet but I guess a lot of people don't like to read.

Coming from a country that uses Metric, I purchased this as some of my woodworking plans come in Imperial measurement, and its handy to have a calculator that can convert between the two measurement types on the fly. This calculator will do that just fine. The only gripe is that entry and conversion could perhaps be a little more intuitive. It is a bit fiddly in some regards but it does get the job done.

Saves time adding mixed fractions, along with adding feet and inches. A more expensive one by the same manufacturer has a few more features but this one does exactly what I want without a large learning curve.

Great price for really handy device. Input process is much more intuitive than other feet-inch calcs I own.

It takes a few minutes to get used to the procedure for entering measurements in this construction calculator, but once you get the knack and start using it, you'll wish you had it all along.

It's perfect for the general builder on site or for home improvement projects. Sure it won't do elaborate trigonometric calculations. But that's the kind of thing you figure out when you're at the computer at home doing the head-scratching work. On site you just want to know how long to cut the board. And you don't want to have to cut it twice because you added or subtracted a fraction wrong.

I didn't realize what a must-have thing this calculator had become until I thought I had lost mine. I was getting ready to draw some shed plans, and there was no way I was going to start until I found the Inchmate. After searching for a while I gave up and ordered a new one.

Of course my old one turned up a day later. But that's okay. Now I have a backup and I'm glad to have it.

I'm a contractor and a sculptor. It's a great deal for so little $ and it works so well. I recommend it.

This tool is very inexpensive, but great for figuring the length of the third angle of a roof, so as to figure the square footage. Also easy to use for math problems when using fractions.
