Sharp EL501XBWH Engineering/Scientific Calculator

Light weight and easy to handle. Though i feel quality wise casio is better.

Cheap Chinese product supplied. Built quality was typically Chinese. Scratches on the screen upon opening the package. Otherwise the product was doing it's job. Had to raise a request for replacement/ refund. Amazon chose to refund, which was done seamlessly. Dis-satisfied with the product supplied but happy with the after sales services.

Qualidade do acabamento é muito boa, com tampa de proteção e facilidade de uso, manual baixei pela internet usando o código nas instruções quem vem, e pelo preço tem ótimos recursos, inclusive conversão para hexa, octal, etc.

I finally retired my 40 year old Sharp calculator - probably costing around $35 at that time - with the same features as this one. It still works - but with sticky buttons and a fading display. This one, with the same features - is an excellent replacement with great value and the reliability of a good company.John B

Prodotto perfettamente funzionante e ottimo in tutto..

In my systems programming work, I often have a need to convert between decimal and hexadecimal base systems. Instead of tying up more precious screen real estate with a calculator program, and juggling that window among too many others that need to be open, I just wanted a simple calculator that could do the task. I was somewhat surprised to find that converting between base systems wasn't more common on inexpensive calculators, like it is in symbolic or graphing calculators. But I already have an old TI-8x series calculator, and it's just too big and goes through batteries too quickly for my simple needs anymore. This calculator fit the bill, and I'm very happy with it.It's simple enough to use that I remember all but the fancier functions quite easily. The manual could have used a little more descriptive text, but I was still able to figure everything out without too much trouble. I probably won't ever use some of the more advanced stuff, but there were a few things that I was pleasantly surprised by, like the ability to convert from decimal degrees to degrees, minutes, & seconds, or Cartesian to polar coordinates, or work with complex numbers.The one complaint is that the front panel is a shiny plastic that is an absolute fingerprint smudge magnet. It looks cool when you first get it, but as soon as you press any buttons, it will always look a bit dirty. Somebody in product design made a poor choice there, but in the end, it doesn't get in the way of what is otherwise a great little calculator.

Buen precio de la calculadora para los precios que se manejan acá en México, el único detalle es que está en inglés, si no tienen problema con esto está excelente.
