Design needs more work
I found the Sonin 2000 to be difficult to use. The largest defect is that if you make an error in entering data, say trying to add 3 feet to 5 meters, the calculator properly tells you that you have made an error, but then it essentially locks up. You can't get back to where you were in the calculation before the error. It has a memory register, but you can't just put a number there, you can only add to the number previously there. Also, the buttons and legends are too small and the feel of the buttons is not very good. (Sometimes the button doesn't make contact when you think it did, and you get thrown into errorland on the next key stroke.)(Sonin didn't reply to my email inquiry about the error problem.) I'd look into other calculators.

I USE THIS IN MY METAL SHOP AND ITS VERY SIMPLE TO USE, AND HAS CUT MY CALCUTATION TIME IN HALF

The basic functions are the best! Need to divide 23 9/16" by 5. Or find out how many inches 24.5cm is! No Problem!

I find I use this calculator everytime I'm in the workshop or Home Depot shoping for materials.

If there's a negative I'd say that the cover can be awkward to close in a hurry. Great tool otherwise!
