HP 48GII Graphic Calculator (F2226A)

I must admit that I am loyal to HP calculators! I bought the HP35 in the early 70's when I was a graduate student at Washington University. I currently collect HP calculators.When I bought the HP 48gII about a month ago I encounted the much talked about keyboard problem. I did what comes naturally. I called customer service. A very friendly representative took my name, address, and the model and serial number of the problem calculator. In about 30 seconds I was informed that a problem free calculator would be on the the way in 3 to 5 business days! I was also given a case number so that I could keep tabs on the progress of the shipment of the replacement. Note that I did not ask for a replacement! The company apparently is on top of the problem and know exactly which calculators need replacement. I asked about instructions for returning the problem calculator and was told to wait for further instruction from HP. If I do not hear from HP in 30 days, I may dispose of the problem calculator as I see fit. What else could one hope for?In four business days I received my new HP48gII with three 3AAA cells and two memory cells. The calculator only reguires one memory cell. I immediately checked out the calculator. My problem calculator would ocassionally not respond to the pressing of the up/down and left/right keys. At times others would not respond. With the new calculator I have not experienced any problems.Go on. Stop listening to the foolishness. Get the best calculator out there. Get the HP48gII!

I have been trying to teach myself business statistics with textbooks purchased through Amazon. This wonderful instrument not only simplifies and streamlines computations, but also helps me organize my thoughts. The sole fly in the ointment is the digital user manual. It is harder for me to use this than the older paper versions. So, I would like to see HP offer traditional paper user manuals with future products. On the whole, however, I am very satisfied and would recommend this product to anyone with an interest in statistics.

I love the line of RPN calculators from HP. Mine that I had through college finally gave out, so I got this one. Took me a little be to figure out how to put the mode calculator into RPN mode (that's reverse postfix notation - not reverse polish notation!). Once I got that then I was much happier!Anyway, the keyboard layout is worse than the older version, but there better menus and on-screen navigation. The speed of this thing is great! I noticed that there are no expansion slots, but I bet that the memory and functions in this one more than makes up for the lack of slots.Oh, the price is AMAZING! 'course I bought mine in college for over $550, while this one was less than 10% of that. So I'll leave plenty of room for the shortcomings of this model, because it's super cheap.Be careful if you let this calculator get cold (like in your backpack on a cold day) - the keys get really stiff and it's hard to input anything. Also, the flexible circuit under the keys can crack if you push a key and the circuit is too cold. This is the same problem with the older model, but just give it 10 minutes and it will be fine.

I bought this calculator because it allows use of the RPN method.The keyboard is horrible. Having the <Enter> key in the wrong place is bad enough, but it often does not register keystrokes. This means one has to make slow, deliberate entries in order to make sure all has been keyed in correctly. The Casio, which I bought in 1987 for $14.95, and that I keep in my field kit, has a better quality keyboard.So far, I have not attempted programming with it; I use it strictly as a calculator. Yet, it has locked up twice in the past three weeks. The only thing that would get it going again was to shove a paper clip down the "RESET" hole on the back.Using the "financial" function is made far harder than it needs to be, its editing function is needlessly complex, and getting back out of financial mode is next to impossible. The instructions for its use are clear as mud.Over the years, I have owned several HP calcs; all of the Singapore-made ones were first-class products. I no longer have most of them due to loss, theft, and in one case, a fire. The 48GII is nothing but Chinese-made rubbish.If Casio, TI, Sanyo, or Sharp made an RPN calculator I would wave good-bye to HP and never look back.

VERE complicated to use, if you just want a graphing calc for your math class save yourself time and monay and buy a used TI!
