Reliable Desktop Calculator, but Stability Could Be Better...
The calculator is reliable and works well for office, school, and basic accounting use. Likes: Good build quality, large display, easy button layout, fast response, and overall accurate calculations. Suitable for daily desktop use. Dislikes: The base does not sit perfectly flat on the surface, which slightly affects stability while pressing buttons. Overall, a good desktop calculator that performs well, but the stability on flat surfaces could be improved.

Always a Casio.
Cute li'l reliable & durable Japanese companion for calculation. Buttons are soft, not so noisy. Good for basic & articulate calculations. It's Lightweight & slightly slippery. So I used the additional rubber pads on the upper part to make it stable. Bottom parts are already having factory fitted rubber pads. Only limitations :- No "-/+" button for sign change and No "00" button for faster typing. It looks nice and premium in front of eyes but photos. For me, if it is a calculator, it is always, anyday, alltime favourite CASIO. I used older Casio calculator (JJ-120D) for 10 years. (2015-2025). It's my second casio calculator. 😆

Mistakes in counting number of steps
Product quality is ok..but the main problem is how it counts number of operations..for example while adding series of numbers if you accidentally press addition symbol two times even without adding any number it'll add it to total number of steps creating confusion..I have never faced this type of issue in other casio calculator

Beware. Indian calculator that uses Indian number grouping
Whilst this calculator has the usual Casio build quality it is an Indian model and uses the Indian number grouping system. While this doesn’t make it totally unusable it does make it difficult to read larger numbers. This really should have been mentioned in the listing.
