Customer Reviews

Advanced
This calculator is very advanced, it has more functions than I know what to do with. The 12c calculator is smaller and has more features than the BA-II. It also comes with a cool carrying case.

HP 12C
This is the third version that I have bought, the first one being in 1984. This item must be HP's all-time best seller in terms of units sold.

HP 12C Platinum
This calculator is the best financial calculator in the world. I would recommend it to anyone looking for a business calculator. Takes a bit of getting used to, but once you do, you will not want to be without it.

HP 35s Scientific Calculator Review

HP 35s Scientific Calculator
From Hewlett Packard

Customer Reviews

Very good, but not quite the glory days
Probably the best scientific calculator on the market right now. Well designed and well built with a proper heft to it. The keys click, which is great, but instead of smooth and rounded like the Voyager and Pioneer families, they're square and wider with a different font.

Overall an excellent tool, but lots of little niggles that keep it from getting five stars and being an instant classic. The case itself is probably the most rigid of all my scientific models, but it's probably at the cost of being a little big, which makes pocketing the 35s a bit of a chore. Being a sort of commemorative edition, it apes the shape of the original HP-35, so the sides curve and has the larger size. The battery door (which covers a full third of the back of the case) annoyingly flexes and creaks, an odd oversight for such a well built design. Fortunately I was able to stop the creaking with some 3M grip tape stuck in the battery area. Something I didn't notice at first but has started to bug me is that the (C)/on key is not recessed or low profile. Accidentally turning the unit on is quite easy. This design oversight is almost bizarre, as every single other TI or HP I have has a low profile on button of some sort. Because the key layout uses distinct arrow keys that only have one secondary function, there were some small compromises made elsewhere in function layout. Most of these can be can argued endlessly, but the one change that was a genuine mistake was subordinating the STO key. RCL and STO are on the same key, with RCL as primary.

High quality product
Thank goodness Hewlett Packard went back to the traditional calculator that made them famous for years. The recent 33s was a complete and utter mess. The 35s is an outstanding scientific calculator for a great price. I would highly recommend this to anyone. Away from the unit itself, the zippered clamshell case that comes with it is nice but overkill and too bulky. A leather slipcase like which comes with the 33s (which I ordered and fits well, and is way less bulky) would be better. Also, they've stopped shipping printed manuals. You have to call the 800-hpinvent number and get to the calculator customer service group and ask for a printed copy. They happily send it quickly for free, but getting it was a PITA. I know everybody wants to save trees, but the target market for this design genuinely expects (and actually reads!) the printed manual.

Those details aside, I'm happy with my purchase.

Piece of Junk
With my old HP42s to compute sqrt(-1) you punched 3 keys: 1, +/- (change sign), sqrt; simple, straight forward RPN. For the HP35S the same key strokes give "INVALID DATA". You can ultimately compute the sqrt(-1), but it takes about 8 or 11 key strokes. Cannot give the exact sequence since I returned the calculator. I feel sorry for anyone who thinks this is a good calculator, they may not have had a real HP before the greed of Fiona. Too bad zero stars are not allowed.

Easy to use
I am impressed by the tactile response of the keyboard. I'm stunned by the features available for the price. (Years ago I agonized between buying a TI calculator that determined square root or an air conditioner. It was hot in my apartment and I had to derive square roots manually.) I especially liked the 4 line display as opposed to the Casio FX-115ES. I have found the ability to retrace more than forty calculations to be very handy too.

Extremely capable despite the low price
My work involves a lot of exchange rates and foreign currency conversions. Really I was looking for a calculator I could program. Enter the exchange rate (which vary from day to day), other conversions like the factor from lbs to kilos. But time was short and a shop with the more expensive programmable calculators meant a special trip into town.

Here in Australia Officeworks (a sort of stationary Home Depot warehouse) have a very liberal return policy (7 days if you're not happy). So on this basis on a Friday night I bought a TI-30XB which is the battery version of teh TI=#)XS with a very attractive bright green in place of where the blue is on the 30XS.

This calculator has the abilty to store 6 constants x,y,z,a,b,c. So in my case I have 2.20468 stored as "x" (this converts lbs to kilos), AUD/USD exchange rate as "y"

For my work the mathview and relatively large screen are excellent. The calculator turns itself off automatically after a few mins if you're not using it. But if you turn it back on, you can scroll back miles if you wish and see all your old calcuations. Plus if you add 2+2 for example you on the next line down use that answer (ans) to do another calc.

awesome for a scientific calculator!
This calculator is really great. A nice upgrade on the regular TI-30XIIS. I hate the <> button because it's where the "+" button should go. But if you just need a basic scientific calculator, or need to do some basic statistics, this calculator is perfect. Not nearly as awesome as the TI83 or TI89, but when you're not allowed to use those calculators for whatever reason this new calculator is way cool! MultiView rocks and so does the pretty math type!

While not strictly programmable I've used the data view (there's a data button to access this) to set up a table showing conversions from USD lb to AUD kg.. one of my main conversions. You can change costs in the first column and they reflect in the 2nd.

I'm trying to go digital here and away from printed Excel pages with conversions etc. Since getting this calculator, all the other calculators in the office are gathering dust. The two features above have me equally won.

For my applications this calculator although not small does the job. Over time we will see if we need a more sophisticated one but at the moment this is working beautifully.

TI...Did you forget to include something with my Nspire CAS?
I'm basically saisfied with the product,but can't begin to discribe how poorly written and incomplete the documentation that accompanied it is. Case in point, my TI 83 plus came with a approximately 500 page manual. In contrast,the much more complex Nspire arrived with a 134 page guide. Can't wait for other publications on this calculator to hit bookstore shelves!

TI-Nspire CAS -- A Product-in-Progress
I probably would have given this product three stars, but I feel that I must balance some of the overly generous grades given by other reviewers. I do not believe that a product that merely works merits a five star rating.

The Nspire CAS has the hardware potential to be a quantum upgrade to the aging TI-89, which is based upon late 1980's processor technology. And yet, at the time this review is being written, the TI-89 is a generally more powerful and easy-to-use programmable calculator than the Nspire CAS.

The built-in software of the TI-89 is very mature, and has much more programming capability than the Nspire CAS. This enables it to run thousands of free user-supplied programs, which can be readily downloaded into the '89 from the internet (via a PC) using only software freely available from TI. The Nspire CAS, by contrast, has no "free" connectivity to the PC or internet. Even if it had this, it cannot run programs written for the '89 due to the lack of many programming features, like input/output and menus.

Possibly TI will remedy the deficiencies in the Nspire CAS programming capability in time, but one should not purchase a product that might be upgraded at some indefinite time when a product that already has the needed features is available right now.

I believe that TI is aware of the foregoing and other deficiencies in the Nspire CAS (many mentioned by other reviewers here). That's why they've priced the Nspire CAS about the same as the TI-89 Titanium, despite the Nspire's superior processor (potentially 3x faster execution), massively larger (20x) user memory capability, and somewhat better display.

In the end, it's the software that does the work, whether on a calculator or a full-fledged computer. The TI-89 has proven to be an enduring example of superb hardware/software integration and value engineering, whereas the Nspire CAS, mostly due to immature software, is a beta product masquerading as a production release.

I am hopeful that the TI Nspire CAS will eventually supercede the TI-89. Given software capability that is merely the equal to that available with the TI-89, the Nspire CAS would today be the superior value proposition. Alas, that's not yet the case.

Does the job....
This calculator does the job for what I need. No batteries needed and it is solar powered. Only problem I have is the cover case. It is not slide in / slide out cover cases like most calculators. It is more of a snap it on / snap it off. Other than that it does help protect it from dust and getting the screen scratched.

good buy
It was sold out at our stores and I recieved it in a couple of days in the mail. Good choice

Great!
I use this for advanced algebra I and it works great as a scientific calculator! (I still have to have a graphing calculator, but that is too big to carry around all the time.) I use this for everything I do math-wise and it works great!

Pros: well...it does what it's meant to do, and does it well. And at a great price, too!

Cons: I left it in my binder without the cover, and I think making it turn on and off all day long broke it. We tried replacing the battery but that didn't work. Also, I like a slide-on cover better than the span-on cover that this calculator has. Still, I am completely satisfied with it!
