HP 300s+ Scientific Calculator

Excelente

Unbelievable value: - Slick design and quality execution - Very nice, crisp display - Good handling of function A very nice product for a very reasonable price

I teach high school maths, so I've really put this thing to the test. All functionality is accurate and quick, as one would expect, the display is excellent and the fractional feature allows me to avoid a lot of confusing brackets. On the downside, the buttons do occasionally fail to register a key press, which is devastating during long operations, but mostly remedied by paying attention and not trusting the thing too much. Overall quite good and it has many convenient features (I love the s->d feature for switching between simple and decimal form, like for geometry answers in terms of pi, or swapping to the decimal form of a fraction.)

I have liked HP calculators since my first one, the 28S, then a 48 and now a 50. I got this to use out in the shop when I don't need all the programmable functions and don't want to put my HP 50 in harm's way. The numbers are big and clear and the keyboard has a slight HP crunch so you know when you've pressed the keys. It shows what you entered on the top line to get the result on the bottom line. Without that, I'm always doing the calculation a second time because I want to be absolutely sure. Some of the entry level HPs have seemed a little cheap to me in recent years but I didn't feel insulted here at all. It's not RPN, but fine for what I use it for. It's a nice basic scientific and I'm very happy with it.

I purchased this for an exam and used it for a week before the exam to become familiar with the calculator. On the 3rd problem entry I encountered an error and found a missing parenthesis. Thought that I missed it and tried to correct but it missed 2 more key presses right before my eyes. I ran a test of 100 iterations of a problem using 15 key presses each. The result was one missed key press in 26 of the problems and more than one missed key press in 12 of the problems. Not sure if I received a device with more than usual issues but this calculator is useless, particularly in exam duty. The features are great for the price but it must be watched very closely or your results will be incorrect. I can't believe HP actually put their name on this device. I have HP Voyager calculators purchased in the early 1980s which still work flawlessly as they did when new. No missed key presses with them. Evidently HP no longer builds any level of quality in their non-graphing calculators. If Amazon allowed less than one star, this item deserves it. Returning this thing today.

The Calculator feels really cheap...I mean, it's an affordable model, but it's really light and weird shaped. I think HP should stick to their expertise and only have 12Cs and Graph models.

I really wanted to like this calculator. Even waited to post this review until I had given myself time to get used to it. It is HP which I'm a fan of for calculators. It looks really nice. It has lots of functions for the money. Problem is the buttons don't work right. I read the reviews that mentioned this but disregarded it and based on one review that said it has the nice distinct HP click (if you own an old one you know that this is) I bought it. It does not. I have to constantly double check the numbers because even though I push on the buttons the numbers don't engage. This makes calculations really slow. The other thing I don't like about it is the screen. It has a LCD screen that is too deep under the plastic protective front, which makes it hard to read unless you are looking directly over it. I like to have my calculator above my notebook and can't do it with this. This I would overlook but the buttons not working unless pushed at a precise angle is not. So I would not recommend buying this calculator. If you are looking for something cheap go with something else that works better. If you want the HP upgrade to a better HP Scientific Calculator that is built with old school HP quality.

I needed a calculator with scientific calculation capability and did not need full graphics plotting capability. This one caught my eye during research and is doing just what I needed after purchasing.

semplicemente perfetta. Con una chiara rappresentazione delle diverse formule rende facile scrivere funzioni anche molto complesse. Le funzioni che sono presenti bastano a soddisfare la richiesta di chiunque. componenti costruttivi buoni, forse essendo lucida tende a graffiarsi abbastanza facilmente.

En la descripción dice q trae una celda solar, pero q necesita batería la cual está incluida y en mi paquete no la trae.. El plástico de la calculadora se ve frágil Tramitaré la devolución

It's a good calculator, but the buttons are too high and needs are solid press to register. This means that sometimes you have to retype the same again; happens especially when you hold it in your hands as opposed lying flat on a table. The screen also, isn't of the highest quality, but it's decent. I will restate that this is a good calculator, it just isn't as nicely build as i ought to be.

Great for teenagers. All the functions necessary for long term study. A level or Uni. Compact and lightweight. Worth the money

Très bonne calculatrice. Touche moins solides que sur ma HP 12c. Mais c'était un autre temps
