Customer ratings and reviews for HP 50g Graphing Calculator

Rated 4 out of 5 by nice calculator, missing % and manual missing a % key or ability. desperately want a physical manual. advertisement on web site erroneously says comes with users guide, but this is incorrect, it's only on the cd and you get a physical quick start guide. I want to know learn how to write programs for this thing so I can solve my problems, prompt for and get user input, etc, but it looks like it's going to be online manuals all the way. I like manuals I can touch and flip through. the manual is going to be 900 pages long though... the HP 33s has a % key. I don't know why with all the financial stuff this does it doesn't have a % key. when I read the manual on base number conversions, it was awful. didn't tell me how things worked. no list of keypresses to enter for the examples, just pictures of the display. no explanation of what the mystery keys/softkeys do. both the quick start and the manual shows signs of being written at high speed and never being corrected. come on, HP, you can do better than this.

Rated 4 out of 5 by Hp50g This is not what I expected, I had hp48g and I loved it, this does not come close to it in quality and ease of access to hp48g. It does not have good screen rsolution either which was really turn off thing for me. November 21, 2010
Rated 1 out of 5 by Quality Sells and the new HP's lack Quality Big Ti I have had a few good calculators in my 25 years of Engineering practice. And they have all been HP's. My last HP which I had for fifteen years was stolen so I went hunting a replacement. I have tried the TI's, the Casio's and others and found all to be built very cheap. They are throw aways. But my past HP's would last and you could tell theyr were well built. Now, I am looking again at HP, have read the reviews, purchased a 33 and I can tell you one thing. They function but are no better than the throw away junk that TI and Casio and others have marketed to the school children. I am a professional and want a professional, well built and easy to use calcualtor. That is what I expect from HP but have been very disappointed with what you are offering. When you all decide to build a solid product again I will gladly purchase it but for now, I watch and wait! July 4, 2010
Rated 5 out of 5 by Excellent calculator but localization is missing. Hello everybody, undoubtedly the HP 50g is a very valuable and powerful calculator and is recommended without hesitation. Nevertheless it does not really support foreign languages, which reduces its use to non English speakers, especially when it comes to higher mathematics and advanced science issues as these require specific vocabularies. Combined with the suboptimal manuals this is a real handicap for non English users, especially in education and this might be a reason why the HP 50g is not as successful as it could be ! A solution to this is the Multi Lingual Pack which truly localizes the whole interface of the HP 50g to German, Italian, Spanish and French including a localized Equation Library (over 300 science and engineering equations) and a localized Economics Library (over 140 formulas of economics) turning the HP 50g into a powerful tool in these languages and making the use of it for a non English speaker a child’s play. Regards, Andreas June 18, 2010
Rated 5 out of 5 by Great Machine The HP50g is a great machine. I had the gold faced HP49g+ for a few years but had trouble with sticking keys, Before that I had the blue HP49g which died suddenly after only 2 years... very dissapointing. The 49g was the replacement from a very sympathetic sales woman. I upgraded to the 50g for the equation library and also bought a 1Gb SD card which I haven't even scratched the surface on yet. Everything works well... there are no sticky keys. The only thing that seems to give trouble is the Clock Alarm feature. If I set a daily alarm it works for a few days then stops going off. Does anyone else know of this 'bug'? Apart from that I have a lot of fun with it and love programming complex graphing patterns for the machine to draw in various modes... wireframe, polar, parametric etc. I also like the black face. It makes it look like a serious piece of equipment. I have also owned an HP41C and the HP48GX. I think overall the GX is my favourite. It worked flawlessly in everyway. It just didn't have enough memory. May 22, 2010
Rated 3 out of 5 by HP 50g A good graphing calculator. Certainly not the "quality feel" of the old HP calculator. Zero key tends to not register multiple presses. If I enter "0.002" I am just as likely to get "0.02" if I don't slowly press the zero key. Generally the feel is cheap but the calculator is rich in features and once figured out seems to make sense. Now if only HP could make their calculators like they used to and they'd become a valued investment and tool like the old calculators were and are! May 19, 2010
