Great calculator, just like the RPN HP-12C but faster. IRR calculation took 5 seconds vs. the 30 seconds on my year 2008 12C. The decimal point is really tiny on the display but I'm OK with that (you can swap , for . if you'd prefer). Included batteries are corroded & unusable, but this product hasn't been produced for some years & this is expected.
The product works well, it's fast, it uses ordinary batteries and has a display great. It looks a bit fragile.
This is, as advertised, a close replica of the HP 12c. It did everthing I needed it to. The keyboard just feels flimsy although Ive not had any problem with it yet. Some of the alternate key markings are hard to read.
Victor V12 is about similar to HP 12C. Victor can also change between Algebraic and RPN. The HP feels better in the hand. But Victor equals performance for a better price. So what is its IRR? The HP manual and Victor's can't compare. HP wins hands down.
my son needed a calculator, it has alot of features, it is a great item my son love it and for the price is great value.
