Review: Works best - Best purchase, very accurate and best calculator. I used it in my bsc high technical questions of maths.
Review: Great calculator in its category - It has a great build, with a really good display, and is excellent in its price point. The major feature of this calculator that sets it apart from its competitors is its full matrix display, where you can see up to a 3x3 matrix as a whole, which can help you in rectifying erroneous values. It is also non-programmable, which means you can use it in almost all exams that allow a scientific calculator. However, a CW version with a better display and more features is available for just 10 rupees more (as of when I'm writing this review), the reason why I didn't pick it is because it might confuse invigilators if you are taking it to an examination, just because it looks more modern, and much more like an actual phone screen with good icons. However, the CW is still non-programmable and allowed in examinations, but you might have to explain if the invigilator is unfamiliar with the model. It also has a front slide-in protector, which can be slid into the back when using the calculator. The calculator by itself is really thin, and having the protector gives a better feel to your hand (and makes sure you don't miss the protector). I have been using it for more than a year now and it has never died on me, most probably due to the built-in self-charging solar option, which charges the batteries as you use it. In conclusion, I would recommend this product over others in its category any day, but if you are taking an exam in a familiar environment or are ready to chat about the non-programmable character, you are better off with the CW model.
