I love this calculator. I've had it since 1992 or 1993, I can't remember which one, but I have never replaced the battery and it's big keys and large display helps when doing bills. This is the one I use for home and business nice, other I have used have not held up as well.

This is the best 10-key ever! Yes, I said 10-key, because after using it for a while, the old 10-key will slide off the back of your desk. It is portable, reliable and works everywhere. You can't run a tape on it, but we have Excel for that now. Trust me, this is money well spent!

This calculator is simply AMAZING. Every single time I try to add or subtract or multiply or find the square root of a number in my head, I get it wrong. This handy little device is not quite the size of a laptop but it is solar powered and never needs to be plugged into a standard outlet. Even though it does not have the whistles and bells like Bluetooth or wireless internet access, it has NEVER miscalculated an equation for me. I carry this calculator with me everywhere in the Sharp brand leather pouch which slips easily into any backpack or handbag. The buttons are large and easy to find. You will not be disappointed with this handy pocket computer.

I have used this model for years and love it. I bought another one for home use!

I am well pleased with the both the service and the product I received. This was purchased for the office and our turnaround time in receiving the items was very good. I do recommend the product very highly.
