Rated 4 out of 5 by Excellent Capability, so-so manufacturing I like this calculator, I actually have two. It is larger but easier to use than my 15c, I like seeing both the X and Y registers and the programming is easier too. The only problem is after a couple years the keys start giving out. I wish it was made better, especially with the $50 price tag. I also wish there was an android emulator. It could be much better with a little effort from HP to improve quality control and provide quality emulators. June 21, 2016
Rated 1 out of 5 by too big -- much smaller HP 15c or HP 32S II too big -- much smaller HP 15c or HP 32S II I lost my old calculator May 14, 2016
Rated 4 out of 5 by A Great RPN Pocket Calculator, Easy To Program This is a great RPN pocket calculator, easy to program.The only criticism is build quality: I've had several units with bad keys. If HP were to upgrade this model in functionality and quality, I'd pay more without hesitation. May 5, 2016
Rated 2 out of 5 by Keys died within one year of office use. The 35s on the surface looks great but under the hood it cant take a year of use in the office? the HP-PRIME , ive been told has a steep learning curve. Ive been using HP's since the late 1970's. I guess I'll do it with a PC program now. April 25, 2016
Rated 3 out of 5 by Substandard UI, but good calculator. This calculator is nice on other aspects than size (it should be smaller 10%) to allow one handed use and its lack of good UI with softkeys (or even a menu) and real variable&program names (..and computer programmability and option to store the programs in microSD). For this date I would have also assumed there would have been unlimited or atleast higher stack like what is in the RPL-machines. Not a real engineering calculator of 21st century. Would have been nice in the 1970's :( The calculating power is nice though, but functionality feels stoneaged. Get old 42s instead or HP50g. Entering of the complex number is smooth though in both polar and rectangular form, easier than in HP50g, but make some searches to find out if the hp35s limitations regarding complex numbers is nogo for you. For these reasons I did only give rank POOR to features, this premium product doesn't meet todays standards. A pretty much visionless, but working product as new HP calculators seem to be.

Rated 5 out of 5 by 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.
