As always shipping done by flipkart was superb, price offered is not so good in compare with other eCommerce site .Overall flipkart return policy and customer support I am happy with the deal .
not to talk much..
pros : my frnd has it from 4 years and the battery still not dead.
now functions and all you already know, i dun bother to type all that sh**.. just go for it. its second best to 991 MS.
i just baught it cz 4 years.. man i know i will loose it within a year :D
This calculator by casio is the best product in the market with many functions. But if allowed in your college i'll suggest buy 991ms which only costs 100 rupees more. anyways this is very good, you'll get all your calculations done by this.
Flipkart's service are always good , but I received 82ES instead of 100MS initially, i called the customer care and they replaced the product i just 3 days :) flipkart is the best, but still try to avoid such blunders :P
This is not just a calculator,it's a mini pocket computer in your hand!
