    The best and most eonomical choice for any science student

    I have been using this for the past year and it has worked perfectly.
    The form factor is just amazing. It is very thin and light as compared to the ones available a few years back. The solid cover is very useful as it prevents the calculator itself from getting damaged. It has everything that a science as well as engineering student will ever need (to do on a calculator ;))

    This does not have the notebook display, which however, i dont feel is very helpful. If you plan on using this calcula...

    Excellent Scientific Calculator

    Haven't bought this from flipkart, but from the market. Price at flipkart is very good.

    Pro: Good build quality. 2 line display, both lines quite large and legible. Reasonably large buttons for easy use. Runs on LR44 cell as backup when light is not sufficient for solar panel to work. Very sleek. Scroll up-down to look at previous calculations. Speedy processor (I use 69! - 69 factorial - as a good calculation to check speed in any calculator).

    Con: Very few and probably very minor. Just wo...

    Perfect

    Working Good. Original. The 991-ms is good for matrix multiplications -3X3 being maximum( I prefer it for that), doesnot support 4X4 matrix. If you need to multiply 4X4 or more go for Graphing Calc(Graphing Calc are not cheap). An alternate solution to graphing calc would be Phone/Tablet Apps which are available on play store and windows phone store as well.

    Review after using the calculator over 6 years

    I have used the calculator since 2004.That time it is the best calculator available at Kolkata. It has almost everything but now-a-days you get more better calculator with graphic display. So, I don't think anyone like to buy this calculator.
