Helect 2-Line Engineering and Scientific Calculator for Accurate Calculations

Elena de Diego Maldonado: Es la primera vez que compro algo en la opción de 2da mano. Estaba un poco incrédula y podía ser que no saliera bien, pero la calculadora funciona perfectamente. Venía en una caja de cartón marrón solamente, pero su caja original no me sirve para nada. La verdad que probaré más veces esta opción si el ahorro es considerado.

Sascha: Tra le più economiche ma con tutto cio che serve per le scuole superiori...Unica pecca che si poteva migliorare è lo spegnimento, se non si premono 2 tasti insieme (shift e AC) la calcolatrice rimane accesa consumando la batteria

HelenB: Calculator, adds things up. Does what it's meant to. A tiny bit chunkier than the slightly more expensive one but not bad.

developer1: I give this Helect calculator 4 stars because it is a pretty good clone of a Casio Scientific calculator, like the Casio FX 300MSPLUS2 - very similar. (So for about the same money, why not get the name brand?) The screen is pretty readable if you look straight down on the calculator, but looking from below (like when it is flat on a desk in front of you) the readability deteriorates with angle and the character background matrix starts showing. In comparison, the Casio FX-115es plus 2nd edition has blue characters on a bluish-greenish screen - less readable in my opinion.

The Helect's buttons are a little loose feeling but seem to work fine. But I found one strange behavior with the RCL memory function that caused me to send it back. I compared it to my FX-115es Plus 2nd edition which works as I expect. So it may be a small bug or variation in the Helect, not a show-stopper if you are attentive, but it tripped me up so back it goes.

Here's what the RCL button seems to do on the Helect: First I store two values, .05 in memory X and .02 in memory Y. Then I press "RCL X + RCL Y =" and it gives me .07, what I expect. Then I press "RCL Y + RCL X =" and it gives me...

Craig: I've had this calculator for about 5 years, and only had to replace it because the two small button-type batteries in it finally died. It had a small cover that could be opened for battery replacement, but the cost of two new batteries was less than the cost of the new calculator. This new one is almost exactly identical to the old one, except it doesn't have the battery access cover. I imagine I could replace the batterie sin the new one by removing six tiny screws and opening the entire back of the unit, if needed. I am a recently retired engineer, and used the calculator daily since I bought it. It is a lot simpler to use then many high-priced calculators from well known manufacturers. If you don't need graphing functions, this one is a good deal.

Old Rogue: I didn’t expect much for $9, but I was pleasantly surprised. No messing about with batteries and such; it worked fine right out of the box. It comes with a nice little (and illustrated) instruction booklet. If you’re not familiar with full-function calculators, be sure to put the booklet some place where you’ll find it. It comes with a nice hard slide-on cover, which you can remove, turn over, and slide it on the back, so it doesn’t get misplaced while you are doing calculations. The best thing though, is the size. It measures 3 ½” x 6”. That means that all the buttons are larger than regular-size handhelds, and feels quite substantial. If you need a full-fuction calculator, you cannot *not* buy this one.
