Sharp EL501X2BWH Engineering/Scientific Calculator

Had them for three years bought three lost one of them. Have one at home one at work and I like the way they feel. It can convert octal binary hex is simple and lasts pretty good so far.

They work

It’s a calculator. It works. It adds, subtracts, multiplies, divides, and lets you use the scientific functions. It’s easy to use. It’s also only $8. Temper your expectations - it feels cheap, because it is. It works great, so it’s a great value for the money. Unless you need functions that are beyond the capabilities of this calculator, there’s no reason to buy something more expensive.

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.

This calculator was made for electrical engineering labs. It does complex arithmetic, and has the most intuitive and easy to use base conversion (binary, octal, decimal, hexidecimal) I've ever seen in a calculator. It's an incredible value for $8. And for the cost, it won't make you cry if you drop or lose it. It has larger more distantly spaced keys for the numerical keypad and arithmetic buttons. It even has a factory reset button if you manage to mess up the settings and want to return to the default. Someone over at SHARP obviously put a lot of thought into this calculator.

This is a good scientific calculator. You can find others with more functions for a few more dollars, but this calculator is a good match for what I was looking for without all the "extras". The key layout is good, the buttons are where I expect them to be (such as the +/- change sign key). The single-line display has good contrast, numbers and modes clearly readable. Keys have a light "springy" touch. Overall, a well-designed and handy calculator.Some reviews mentioned theirs arrived with corroded batteries. The two LR1130 batteries pre-installed in mine look new and the battery compartment is clean. Be aware that the product listing says this calculator uses two LR44 batteries, but it actually uses two LR1130 batteries (consistent with what is also stated in the manual).

The calculator buttons are a little noisy if you shake it and it feels a little cheap but it works good so far and is easy to use with many functions, I will probably buy another one sometime in the future. The cover is nice and fits well. For the price I would recommend.

I bought this calculator because one of the reviews said it handled complex numbers well. I find that is not the case. While entering a complex number, while strange, is possible, manipulation of the complex number is highly limited. You can add, subtract, multiply and divide. But you cant use any of the other functions such as sqrt, x^2, x^y, log, sin, etc. I was not surprised by the exclusion of the trig functions, but excluding sqrt, x^2 and x^y is very bad.

Ótimo produto

It's a nice calculator. Has all the functions on it, and is easy to use. It also comes with instructions for the more complex functions on it.

Prodotto perfettamente funzionante e ottimo in tutto..

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.

bought for my son's they're happy with it
