Has lots of great features that typical calculators don't have and make life as a contractor much easier. Lightweight enough to carry with you on the job site. Durable enough to just throw it in the toolbox. Most important, it's accurate. This was a great stocking stuffer this year.

Rated 5 out of 5 by from Perfect tool for conversions I recently bought several Festool products which are German made, so all the scales on these tools are shown in the metric system. I purchased this calculator to do the conversions from metric to Imperial because that's the system I'm more familiar with. It's extremely easy to use, you simply input the number you want to convert in millimeters, hit the inch key and your done, obviously it also works converting inches to millimeters . The screen is large, so even if you wear glasses for reading you'll have no problem seeing the numbers. This unit can also be used for just about any calculation you can think of when it comes to construction projects. Way too many to list here!

Rated 1 out of 5 by from Inaccurate with fractions I'm a master carpenter and woodworker. I work in fractions of an inch, this calculator can be as much as an eighth of an inch off. The manufacturer is aware of this defect, they address it in the implied warranties, stating that no guarantee is made for accuracy and it is sold "as is"

Rated 5 out of 5 by from Best Calculator on the market! I've used this model for many years and sent it to a friend who loves it as much as I have. I used to use it for construction design----absolutely invaluable! Now it's relegated to do the mathematics of knitting design and is still invaluable..
