Summary: I have used these since the original "48G" came out. I bought this for a family member since I have had such great performance out of my original model. This is a LOT of graphing power for the buck. Since 1974 I have owned many different HP calculators. Not one of them has ever let me down.
A very valuable instrument at an extremely reasonable price.

Summary: 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.
A cost reduced version of the HP 49G+ calculator, retaining the functions.

Summary: The HP 48G II belongs to HP's HP-49 family (49G, 48GII, 49G+, 50G) and was released as a mid-generation together with the HP 49G+. Besides having slightly smaller display, less memory, slower CPU, reduced equation library, no SD-card and not being able to update the ROM, this was otherwise functionally identical to the HP 49G+ and comes with the same +2300 functions and programming features. This means it's a very capable calculator indeed.
Summary: Do not buy HP calculators manufactured in China. The keys only work when they want. I always bought HP calculators including those made in Singapore. They had great quality. But these Chinese HP are a disappointment. If you do not want to have hassle, then do what I do: buy a Texas calculator.
