Texas Instruments BA II Plus Professional Financial Calculator [並行輸入品]

I have both the BA II Plus and the Plus Professional. The professional is more expensive, but the extra cost is worth it. I am not sure if it was just my calculator, but the BA II Plus felt cheap. The buttons were not very responsive, so I would type 1.1 and get 11 instead, and the screen was very small. In an exam, you don't have the time to re-calculate over and over again. Aside from cost, the Professional doesn't come with a cover face plate, so you need to maybe buy a carry case, but it's such an easy decision.

Perfect for MBA courses

試験に本当に役に立ちました。なかなか使いやすいです。機能もちゃんと整えてくれるから、推薦します。

説明書を見ても基本的な使い方を理解することが困難。読むのがめんどくさくてマジ吐きそうになったので、Youtubeの解説を参考にしたり、CFAの演習問題に取り組むことで少しづつ使い方を覚えていった。また、付属品である袋のサイズが明らかに小さく計算機にフィットしない雑な作りになっていることを付け加えておきたい。

Nothing to complain.

CFAの試験用に購入しました。ボタンは押しづらいし、気を付けて押さないと認識してくれないこともあるので改善はしてほしいのが本音です。 でもルックスはいいし、試験で使える電卓は限られているので結局気に入って使っています。

販売代理店のペダルマニア音楽館という業者にご注意ください。外箱や緩衝材による包装が一切ない状態で配送され、届いた時点で商品本体に目立つ傷がついていました。すぐに返品・交換を検討しましたが、商品自体はかろうじて動作したため、そのまま我慢して使用を続けました。しかし、使用開始からわずか3ヶ月で完全に故障してしまいました。品質の悪さにも驚きましたが、それ以上に問題なのはアフターサポートです。連絡を取ろうにもメールでの問い合わせ窓口が見当たらず、記載されていた電話番号に連絡したところ「使われていない番号」となっており、一切連絡がつきませんでした。金銭的・時間的な損失が大きく、非常に残念な買い物になりました。品質管理とサポート体制に強い不信感を抱かざるを得ません。購入を検討されている方は、十分にご注意ください

特に動作不良もなく良好な動作。説明書は英語だが平易な英語で書かれているため特に問題は感じない。

Se paga sola, increíble calculadora, sin dudas la mejor que he tenido. TVM mas facil que con Excel

I own both this and the regular BA 2 plus. They have the same functionality but the build quality on this model is much better in every respect in which they differ. Both models share the same weaknesses, though. Strengths: * Allowed on the CFA exam and in many finance classes. This is the real reason for its use * Has most finance-related functions you would need reasonably handily available * An alternative to the ubiquitous HP 12C * Has both chain and algebraic mode. Chain mode calculates everything up to now immediately, so 2+3*5 = 25. It also has algebraic mode, which would give you 2+3*5=17. Some people like one way and some like another. I'm glad they provided both. Personally I use algebraic mode but you have to get used to it. Weaknesses: * The biggest weakness in both this and the regular BA 2 plus is their decision about key presses. You CANNOT press a key until you have completely released the previous key or it will not register. This leads to big problems if you are typing fast on it. You really have to use the same finger for all keys you press or some of your key presses will not register. You may think this is a small problem because this is how many people use a calculator. However, the BA 2 plus has many important functions that you can only get to by pressing "2nd" and then the key. It would be very desirable to be able to press second with one hand and the key with another. I can't tell you how many errors this has caused for me. I think TI had to implement this on purpose, so I have to blame their engineering and/or design department. The HP does not have this failing. * Screen construction. The plastic over the screen is really, really thin and in contact with the LCD. This means a very gentle touch will turn your LCD black or put crazy designs on it. This is problematic since this calculator only provides a soft case and the screen is not recessed, so the screen WILL get pressure applied at times. No need to make things so delicate, TI. * Friction with the table. The regular BA 2 plus has no friction between it and the table so as you type, your calculator will move around. Awful. This pro model has two small rubber bumps at the top of the calculator but the bumps at the bottom are plastic with no friction. This means the calculator has a tendency to rotate as you use it. I don't know why TI didn't just use rubber at the bottom like they used it at the top. * Interface design. This is not the worst design in the world, but it does seem like the guys at TI could have put more thought into which functions are frequently used in finance. For example, you must press "2nd" in order to use the exponential function. That's a very common function in finance! They made really obscure functions like inverse hyperbolic cosine as easily available as really basic and important stuff. Another example of a poor decision: it takes multiple keystrokes to clear basic items like the values stored in the time-value-of-money spreadsheet or the memory locations. Why make these commonly used key so obscure. What TI really needs to do is video people actually using this calculator on the CFA and in classes and see which keys get used. Make them easy, preferably one keystroke. Bury things that are *never* used in a menu or something. Neutral comments: * Some people say the keys require a lot of pressure to press. This is true but it's also true of the HP and generally, I think, a fine choice. They could have made them more gentle, but these positively click, so you really know when you have pressed them. You won't accidentally press wrong keys. I think it's fine. Anyway all three main financial calculators (HP 12C, BA 2 plus, BA 2 plus pro) have high pressure keys.

Chi acquista questa calcolatrice ha l'esigenza di avere uno strumento utilizzabile per l'esame CFA, e questa T.I. è il meglio sul mercato. Al di là di questo specifico impiego è comunque un'ottima calcolatrice finanziaria. L'ho acquistata con Amazon Wharehouse ad un prezzo di circa un terzo, ancora sigillata nella confezione originale. Soddisfattissimo!

Good quality

Très complet et utile pour les études liées au "corporate finance", accepté aux examens; pas de programmation possible. A noter l’écran se marque de taches noires lorsqu'on appuie dessus...sans conséquence, l'écran redevient normal au bout de quelques secondes. Les touches font néanmoins un peu de bruit.
