 - Calcultor HP 50gIs a good product the best thanks to the seller for your price is amazing Rating:  - Not for general useOh how I wish I hadn't spilled soda on my 32sii... I purchased the HP50 as an upgrade/ replacement for the 32. I've owned several HP RPN calculators over the decades but I can't get over how awkward this unit is to use. The manual is terrible at explaining the functions, it seems to be random on when they explain step by step versus vague descriptions of the features. I still haven't figured out how to do a conversion between liters and gallons rather than having to remember 3.79. This thing will be a brick for all but the most devoted users. I now know why people are willing to pay several hundred dollars for a used 32sii. Rating: - Puntuality and responsabilityThe product arrive very fast. There are not problems with the product, all fine. I recommended. Rating: - Not a step down from the HP-48GIt was inevetable my 48GX would croak someday. Someday turned out to be last week. I've been running the SMI BCE COGO land surveying software on it since the mid 90's. Although it hasn't gotten a lot of use since affordable COGO/CAD software for PCs became available, it was handy enought as a backup for doing quick calcs. replacing it was a necessity. The 50g is running D'Zign's Basic Cogo+. Because of its more rounded contours it feels more comfortable than the 48 when cradled in a two-hand hold, and has a pleasing heft to it. The keys have a positive stroke to them when doing two-thumb data entry, and the display is easy to read under flourecent lighting. Too bad it won't talk to the little thermal printer I used with the 48. Rating: - HP quality is back!Having owned and used a variety of HP calculators over the years, I've seen the build quality drop steadily. For example, I still have, and use, a HP-12C financial calculator that I bought in the early 80's. It's far better made than the current versions, even with the feet and silkscreened print worn off the back, and retains a like-new feel. HP's recent calculators, whatever their level of functions and features, have felt pretty cheesy. With the 50g, HP has made a big step back to quality. It feels good, though it doesn't rise to the quality level that originally made HP famous. But with the features, flexibility, and speed it provides, is really the best scientific calculator available, once you get past the religious arguments of TI vs HP. If RPN is hanging you up, don't let it. The 50g supports a number of notational approaches. The other principal objection to HP calculators vs. TI reduces to simple familiarity, as TIs are almost universally-used in school settings. If you are a TI user, you will find that switching is trivial. Those who do sometimes report an interesting reaction - feeling betrayed by the schools when they realize just how much better the HP is! I do agree 100% with other reviewers that the manual is a big, big disappointment. Count mine as another vote for complete, spiral-bound manuals.
