cooolest device for an engineer

this is the best calculator an engineering student can ever have. the best pal, chum and friend for ur examinations.Also the most sensible buy then its competitors like BISTEC ,TI can have.
I can however assure u other casio calculators are there in the market but nothing beats this perticular model 991ES on the engineering front. Even for the complex calculations of various roots and surds this calculator comes in handy just like a soldier's ASSAULT RIFLE in the war so it is for an ENGINEERI...

Simply Best Calculator

I was using Casio fx991 ES earlier. This is an upgraded version of that CalC and hence it is sx991 ES Plus.
>>This CalC is allowed allowed in almost all other universities as it is non-programmable.
>>It is very handy to use, display is perfect and also, I can see some upgrades in simplifying Complex numbers and Vector calculations.
>>Best part is its UI. Very easy and readable/Writeable UI with real life appearance.
>>Equation solving, integrations, differentiations can also be done easi...

Quality Hit- From Flipkart Edit: Refund Recieved

I got the Product delivered next day after placing order with one small issue(solved)
I placed the order on Sept 30 for Rs.769, Next day the price is dropped to Rs.707 as "Deal of the day".

The Customer care Executives are helpless, extremely Sorry! shedding crocodile tears.

Other competitors were offering same for less but flipkart choice was obvious for Quality SALES & Service.

I was just unlucky or sucker for such depreciation .

Once bitten, 10 times shy.

A Good Calculator for Eng Students!

I bought this calculator for my son. And he is perfectly happy about it..exactly the one that he wanted.

As for quality, there is nothing new to say about Casio products. People are using them for generations. All you need to make sure is that you buy a genuine one.

With FlipCart, there is no need to worry about that.

Delivery was, as usual, prompt and came with good packing.

By the way, I found this calculator is about Rs. 100 cheaper on FlipCart compared to open market price in Bangalore.

Not much of a difference over the 991 ES

Glorified screen, and the integration functions becomes a lil easy to enter. the 991 ES is still better. This is a lot flimsy in construction. Fell of once by mistake and the solar panel has been wobbling. The ES (old version) however was very sturdy.
