Huge functionality with some annoying quirks
This calculator has tonnes of features such as spreadsheets, equation solve, differentiation, integration, etc. However, compared to TI calculator, casio has included some annoying quirks. The 2 major quirks are that the calculator does not save history after it has been powered down and you cannot select a solution from history to include in current calculations. There are many other quirks which can be found in the user manual which can be found with a quick google search. Overall, this calculator is great only if you are willing to learn and work around the dumb decision. If you don't need the level of features that this calculator offers and just want a scientific calculator that can solve equation and differentiate, you might want to look at ti 30x pro. Although i haven't used that exact model. assuming it's similar in terms of UI to the ti-30xb which i have used, it should be less annoying to interact withRead full review

Express shipping to get box and user manual?
Overall the calculator has no issues, it works great. What I don't get, however, is what are you going to do with the extra box and user manual? Why not just include them? It seems like an unnecessary restriction to put on customers and the price of including the user manual shouldn't warrant the extra $6 for express shipping.

It's a great product
It is a new calc still not approved at some places, so check before buying. It has a solid feeling when using. So far the best scientific calculator i have used. Other calculators feel cheap, but this has kinda the feeling many people would want. Carbon fibre like finish and some metalic keys. Overall key tap experience is great

Great Calculator
This calculator has many functions which can be useful to any students especially those who are studying engineering. It comes with the original box and its manual for reference. I highly recommend this product if you are looking for a scientific calculator.

Parcel Delivering is late
Casio fx-991 series (previously I've got an fx-991CNX) is the most powerful scientific calculator I've ever known(exclude graphic calculators). That is why I choose the very model on helping on my assignment and even calculations on exam.

Update
Calculator used Only fews day and then run out of battery. Don’t think a new calculator would run out battery at this fast. I’m sure that this is a second hand calculator. However it can be recharge by sunlight.
