Customer Review: Buttons skip: Frustrating!
Summary: 2 Stars
The buttons skip. When I press them, the buttons give a reassuring soft click, designed to signal to me that the number has been entered. But frequently the number is NOT entered, even though the button clicks. The result is that I get wrong results and have to repeat my work. This is immensely frustrating, and it seems to happen mostly with a few digits (0, 1). The whole point of a tactile button-click is to give feedback that the number has been received. Because of what must be shoddy design or manufacturing, my unit is unreliable. Because it is unreliable, I have to double-check my entries--which slows my work down--or I have to press extra-hard on every button (which gets wearing when you have hours of work to do).
How can a simple product like a calculator be so hard to get right? This is mature technology, apparently from a leading company in the field, but it cannot do the job reliably. Making a calculator look flashy is secondary to making a calculator that does its work and does not waste my time repeating my work.
Customer Review: Slow key responding
Summary: 2 Stars
First, it's a product review. (Shopping with Amazon has been a pleasure)
The design is cool and stylish, but don't be fooled by its appearance, cheap synthetic case too. (can't believe ppl say it is nice! it's not even napa leather) I pefered the hard case as it protects the on/off key. This calculator has turned on twice in my bag.
Very hard keys and slow registering, if you have fast fingers and like to enter numbers using both hands like me, then this is not for you. You have to press the numbers one by one slowly to have them registered, i used to work all my Fin. functions on a TI-83(no problem at all) which is not permited for the CFA exam.
I hated the Plus Pro after comparing this with the Regular Plus. This calculator slows me down for CFA exam practice problems and i had more than few errors cus of numbers not registering.
The manual and function algorithms are very good though, require min. learning curve. Calculation speed is faster than the Reg Plus's.
Customer Review: Excellent functions, friendly user interface
Summary: 4 Stars
I needed a financial calc but wasn't sure which to get. I knew of the HP series but found them archaically obsolete with so many ridiculous keypresses you have to basically memorize through route repitition and they are quite slow. I didn't want that. I wanted to use modern technology to assist me. In this case, the BA2+ has an intuitive interface with the labels for keypresses appearing on the screen itself and scroll buttons to make your way through worksheets. This allows for easy entry without having to memorize anything. Finance can be difficult enough -- no need to make life harder for yourself.
The functions are great, with everything you need. I enjoy the algebraic entry mode such as using stacked parenthesis order of operation. Coming from a TI-89, this is a very natural way of doing mathematics for me.
Only negative I find is sometimes pressing a key rapidly doesn't register. I can't find any regular pattern to this so am unable to offer an explanation.
Customer Review: Nearly unsuable
Summary: 2 Stars
This calculator performs all the functions you'd expect of it. In terms of actual design, the only thing additionally I'd ask for is perhaps a second line on the LCS for reviewing calculations algebraically.
But there exists one huge problem. While the buttons give a very positive *click* when you press them, it seems about one time in 10 or 15 the key press fails to register. As I normally touch-type on the number pad, it renders the device next to worthless. The only way to ensure you calculations come out right is to stare at the screen after each....and....every....key press. That might be great for high school kids taking a finance class, but it is worthless for the "Professionals" the product name would imply might use it.
The only thing keeping this piece of junk from getting a single star from me is that yes, it does technically work. But only if you watch it like a delinquent 12 year old.
Customer Review: Worst key entry ever!
Summary: 2 Stars
This calculator looks nice and has great functionalities no doubt, but it's the worst key entry experience I've ever had with any calculators! The keys are simply too hard and one would need to exert a lot more force down on each of the keys for the input to register. As such, like many have complained in the previous posts, this makes calculation extremely slow, not because the calculator itself is not able to perform the task, but to punching in all your numbers would simply take too long and too much effort, with the added risk of not being able to enter everything correctly because the key pad is just so damn hard to press!
So frustrating! Why can't they just learn a thing or two from the casio fx series, once you've used those calculators you never want to touch another one again. Too bad casio doesn't make cfa approved calculators.
I'm starting to really really hate using this calculator.
