CATIGA Programmable System /Scientific Graphic Calculator CATIGA CS121 - (White)

The calculator works for what I need at a decent price. Its buttons are able to be read clearly etc and it gives the correct answers. Just two little things. 1) the actual calculator seems rather flimsy. Like if an average weight adult steps on it they will break the casing which is not brilliant but I use it at home at my desk so no big deal but still -1 star. 2) the supplied batteries came empty. I had to buy new batteries. That happens sometimes regardless of any products price point, so that didn't affect my rating. Was just a minor inconvenience.

It does all the things even things I don’t need.

Got this out of nostalgic curiosity for the days before use of calculators in schools shunted programmability to top end professional devices. AFAI can make out it is similar to the old Casio fx-6300g kit. Pleasant for taking me on a trip down memory lane but these days, if you want a programmable device, then I think you're better off getting a top-of-the-line model from one of Casio, HP, Sharp or TI. (I use an HP50g, which beats the pants off this Catiga offering.) It's minor saving grace is that it's probably the cheapest programmable you can buy.

Said it is a graphing calculator but cannot figure out how to graph with it. Got many math teachers to try and no one can figure it out

very handy exactly what my daughter needed
