Use full product for all purpose

It was very much useful in my college for calculating and it actually works good

Value for money...Best Choice in this prise range.

The calculator has pretty average build quality. The buttons are wiggly. I used it for about 10 days now, and it is working properly so far. The only problem I felt this far is that it sometimes doesn't read the key that I touch lightly unlike other calculators I used before. So if you are looking for a cheaper calculator with average build quality that works properly, you can consider buying this one

it is a good product, functions well as compared to some other calculators by brands like citizen etc. It performs all the functions of a scientific programmable calculator and on top it has a solar charger on board. The build quality on the other hand is mediocre at best as within 6 months of use, the front black plate came off on its own other than that it is fine considering its price point and serving its purpose.

Satisfied with this calci...

Calculater quality is very bad and companies customer care service Is really bad no answering when calculater is not working. this company is like fraud company. When calculater doesn't working and 3 years warranty but company doesn't replace the calculater I have suggested to all do not purchase this companies calulater. Zero rating
