 I am satisfied with my purchase. June 11, 2007
Order arrived in the condition I expected it to be in.
 Really Poor November 11, 2006
5 out of 5 found this review helpful
I first purchased the HP 48GII about two years ago. The first one didn't last a month, but HP quickly gave me a new one free of charge. The second one ran better, but the keyboard was very uncertain and often caused input errors. NOT GOOD and very frustrating. Well now the keyboard has failed all together and the calculator won't turn off. This is REALLY POOR merchandise! I do not recommend anyone purchasing this calculator. Unfortunately I've heard that other current HP models are just about as bad. My old HP 41C lasted nearly 20 years...I don't understand why the new ones are so cheaply made. ///
 Had it for 18 months, then keyboard started to break April 21, 2006

Pros: This calculator (and presumably other HP 48/49 calculators) has an operating system that far surpasses TI's in usability. The angled keys are really nice to use, when they work.
Cons: Too bad it is hard to use a calculator with a broken keyboard. The bottom row's hinge have almost all broken, so the keys are really loose and wobbly. Apparently, the plastic hinge mechanism is really weak and this is a common problem.
why not get a HP49g+? Look at the price! June 17, 2005

at the time of writing the HP49g+ is available on
amazon at $77.99. Since the 48GII is a 49g+ with
features removed - why not get a 49g+ ?
Hold on to your 48GXs January 26, 2005

I had high hopes of this calculator being a "real" 48G, maybe with a faster processor running an EMU, but the original case/key design and ROM.
My trusty HP48GX no longer functions properly, the 3, 6, and 9 keys fail to register when pressed.
Bill Hewlett and Dave Packard would join me in my sadness and disappointment at the lack of innovation at HP, and the pathetic replacements offered to the fine 48GX, the lowly, rubber keyed, algebraic entry, plastic faced, 49G and 48GII (both of which I have tried and rejected).
Upon inquiry to HP customer support about the possibility of getting a 48GX repaired, it became apparent that the cheap printers they make, Carly's merger with Compaq, and Hewlett Jr.'s denouncement of the company's current direction are indicative of the level of service and quality of customer support technicians hired by HP, [...]
While searching for a replacement for my 48GX, I encountered a strange phenomenon, used HP48GXs are selling for twice what the new flagship HP calculator costs, and as much as $400-$900 for the few unused 48GXs still around. This is a testament to the failure of HP to continue to provide innovative products, and to the brilliance of the engineers and programmers of the original 48GX at the now defunct Corvallis research facility.
How can a nearly 15 year old technology product still remain the most desirable and sought after in it's class? Only through initial brilliance coupled with the failure of executive management to develop and support the innovation required to improve such a product rather than trying to replace it with a lesser machine. What right-minded consumer would purchase a 49 to replace a 48?
Alas, we have witnessed the demise of the only truly innovative producer of engineering calculators. What does the slogan "HP Invent" mean today?
The talent behind the last several 48G ROMs, Jean-Yves Avenard and Gerald Squelart have given me renewed faith in the future of calculators. After being fired by the new HP, they have taken it upon their selves to create the finest calculator in the world, the Qonos, and I eagerly await it's release. [...]
In the meantime, I am about to embark upon an all-or-nothing attempt to service my own HP, a process which involves a drill press, razor blades, and surgical precision in hopes of extending it's life once again.
Good luck, and protect your HP from cheap batteries and wrong-doers at all costs.
