HP 300s+ Scientific Calculator

Excellent value for the money. A lot of functionality

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 bought this product because it has "HP" on it. I collect HP scientific and scientific graphing calculators. Comparing this with other HP models, it is basic and uncomplicated. The display needs younger eyes or magnifying glasses to read the status symbols. It has the look of a Casio calculator, even down to "OFF" as a shifted [AC] (All Clear), rather than a shifted or toggled [ON]. That is a hallmark peculiarity of Casio scientific calculators going back to the late '80s. Aside from those points, and for $15, I find it acceptable and easy to use, and a good fit for middle and high school math where calculators are permitted. It is also acceptable for professionals as a basic tool, though I recommend the HP 35S for professionals if graphing features are not needed.

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.

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.

bought this on a whim to amuse myself. I am fan of RPN and this one is not but I was bored and wanted something I could leave in my car or office or whatever and not get too mad if it gets lost or stolen. I do not like the keys that much and the keys do not register sometimes unless I push them firmly.....other than that, it works fine.

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.

MUY UTIL PARA LA ESCUELA, BUENA CALIDAD

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
