Customer ratings and reviews for HP 50g Graphing Calculator

Rated 1 out of 5 by Way too complicated I had my HP model 28-S scientific stolen and I replaced it with the 50g. I have spent hours practicing on the calculator and it has proven to be too difficult and cumbersome for everyday use. I am a Professional Mechanical Engineer and I would like to think I am capable, but navigating thru the 50g is too much. Anyone have a 28-S they would like to sell? September 8, 2011
Rated 4 out of 5 by replaced the 48g calculator My old HP 40g finally gave up working. The "on" button became unresponsive, and when i tried opening it out of desperation, it wouldn't go back together. I did some research and found that several other models of calculator didn't have the same "feel" of the 48g. However, I liked what I saw of the 50g and took the risk. I'm glad I did. This calculator, while not exactly the same in feel, is solid. It even fit in my old zippered 48g case (the one that comes with this one is cumbersome and has no inside pockets, so keep your old case if you're replacing a 48-series). The buttons have the classic "click" feel. It took a few tweaks to make it work like I was used to, but nothing too difficult. It's more on-screen menu driven, but the interface can be made to be identical to the 48g. The was an odd key delay problem I had...if you push the keys too fast, it couldn't keep up. However, that was changable by changing the "keytime" system variable to 500 (a quick google search will turn up detailed instructions on how to do that...it had to be entered manually). Once I got things tweaked, I've very satisfied. The key placement is very similar (aside from the "enter" key) and the new placements are simply ones I'm getting used to. If your old 48g (or older) calculator still works, keep it. If it's wearing out like mine was, though, this is a solid replacement for it. July 10, 2011
Rated 3 out of 5 by Powerful, but why the poor support? I think that this is a very useful and powerful calculator for engineers, scientists, mathematicians,etc., but I have to slam HP for they way they support it. Why is HP so lack in supporting it? The software for connecting to a computer is years out of date. Why is HP still selling these if they don't want to put some time and money into keeping the PC software up-to-date? Also, what is the deal with the manuals? PDF is fine, but here I have this awesome calculator that can do so many things but in order to use or refence the manuals, I have to also carry around my notebook computer to read them. HP, please provide a nice printed manual to accompany your swell gee-wiz calculator (like your competitor does). Then there's the SD card slot - a great easy way to expand the memory capacity, but I put a formatted 1GB SanDisk SD card in it and then use the File Manager to view it - 991696KB. Then I insert a formatted 2GB Sandisk SD (not SDHC) card and the File Manager shows only 934592KB - less than the 1GB. Do any of you others out there see this happening or is it just me? Both cards are formatted FAT so I don't have to wait the extra two seconds every time I turn the calculator on when they are formatted FAT32. BTW, if I format the cards using FAT32 the capacities are even less than FAT. That's what I think of this calculator so far. Very nice but HP dropped the ball on the support side. Thanks for reading my review. June 3, 2011
Rated 4 out of 5 by HP 50g Found online much cheaper than at HP.com, however, with that said. It is solidly built, keys have a good feel, still learning the functions, but it works very well. April 8, 2011
Rated 4 out of 5 by Wisest Purchase over TI Product First off to say is that I am very pleased with the performance of the HP 50G calculator. It is a very handy tool for students and for professional. I have been using it for about 6 months now and still am amazed and learning some of the things its capable of doing. The functionality of the calculator is very suffice for a wide range of fields of study. IT is a calculator geared towards science and engineering applicants and is a fine tool to have by your side. The graphing is very good and crisp. I rarely used it up to this point, but as a engineering and applied math student, I would be it will come in handy for analysis linear relationships of components or exponential graphing. Definitely would be helpful when it comes to dealing with intermediate wave analysis results, but then a computer would be needing to do the details I would think. I definitely love the textbook format entry of data inside the equation writer and the ease of use with the matrix writer, unlike the TI-89. I was not used to the different style of computing with RPN, but I have grown to love it's way of making complex calculations simple by breaking the problem up in smaller pieces of calculations. It is something worthwhile to learn to use. Also, I love the fact you can do internal programming on the calculator itself and store it as a variable in VAR, or do external programming in a compiler and then transfer your data programs over to the device. Another thing I love on this calculator when doing laplace and inverse laplace transformations is the (copy, cut, and paste) buttons. Along with the equation writer and as well as parttial fraction decomposition "partfrac" is a breeze and very satisfying. Also had functions for the laplace, inverse laplace "ILAP" and laplace "LAP". But there are many more things to love about this calculator, these are just some of the few that I have liked. The keyboard layout is very simple very much like the TI-83 but more more sophisticated like the TI-89. I believe it does not take long to get use to the keyboard layout and functionality of the calculator with a little practice as it would with the TI-89. The are very good tutorials online with examples so you can see with applicable problem solving of how to do these things. Oh almost forgot, I love the use of the step-by-step solution process of a problem. That is very useful tool when learning something to see how the calculator process takes of doing the problem. One thing it could be used for is when learning matrices and doing Gauss and Gauss-Jordan elimination. The calculator will step you through the matrix row reductions and show how they did it at the top of the matrix. All in all, I would say, why haven't I been a user of HP, but I am glad I am now and I think I would never go back to using TI, except for maybe if I have to, then it would be my TI-83, because that was my first and only graphing machine before purchasing the HP 50G. Thats all I have for now. Really consider the uses you will use the calculator for and compare with other and just make the right decision for you. February 12, 2011
Rated 5 out of 5 by key delay Mr. Hagio, good morning. About the multiple zero key pressing issue, you can fix it with the following command: 500 (or some other number of your choosing) ENTER ->KEYTIME (remove the space after the arrow) ENTER just do this and it will be perfect again... I have this issues since the 49G calclulator, the 48G/GX did not have this kind of problem... I hope it helps. December 17, 2010
