Rated 5 out of 5 by from A Great Programmable Calculator I bought this on the strength of HP's record of great calculators. It comes with a case and batteries, a CD with the manual and quick start guide. It uses RPN, is straight forward to use and program. It is a successor to the first HP 35 calculator and has that great styling that other HP calcs have lost. I'm very pleased with the purchase.

Rated 5 out of 5 by from Love RPN, Hex mode could be better It's rather annoying that when in Hex mode, entered numbers still default to decimal. Entered numbers should default to the current radix mode.

Rated 5 out of 5 by from Excellent product! I have owned over a dozen HP calculators starting with the HP-35. The 35s and the 45 were/are the best of the lot.

Rated 5 out of 5 by from HP hit the nail on the head HP has done a great job with this calculator. While it's not built exactly like the classic series (HP-35, HP-65, etc.), it is still a fine calculator. I bought this to use for the FE (Fundamentals of Engineering) Exam because NCEES does not allow the 50G. Even though I'll only need it for the exam, I do not see the money I spent as wasted, as this will be a nice complement to my 50G and other HP calculators. I was a bit concerned about it when I read some of these reviews. One review said that the character for "theta" was too close to the character for "8" because it differed by only two pixels. While this is true, I do not find it annoying. Another reviewer said he was annoyed because the negative sign was not vertically centered in front of the number. This is also true, but again, it's not too bad. Someone said that "LASTX" was gone. I guess he didn't look too hard, because it's right on the enter key! Yet another complaint was that the "STO" function was on a shifted key. Come on, is it really that hard to press one more key? I think the calculator could've come with more of a "case" (mine's more of a slip cover), but times have changed, and leather cases are a thing of the past (even my 50G came with an imitation leather case). All in all, I think HP has done a good job with this calculator in that it is useful, functional, and looks like the classic series of HPs that so many engineers (including myself) have grown to love so well. P.S. The first 35s I ordered had a problem with the "5" key. It needed to be pressed slightly harder than the others to get it to register. I called HP and had a replacement in two days, no questions asked. I even got to keep the first one!

Rated 5 out of 5 by from finally a calculator that matches the 32sII The only calculator in 20 years that matches the style and ease of use of the HP 32sII.

Rated 5 out of 5 by from Great This is the closest I can come to the HP45 that got me through engineering physics. I worked two summers to raise the cash for the 45 back in the day. RPN, two line display, functions beyond 1975 imagination, and batteries that last 30 months, not three hours. Living science fiction. Cool.
