    • Lighter than the fx-115ex same speed
The calculator is light, very modern look but is not considerably faster than the fx-115ex I will venture to say that is the same speed

    • Leaking battery
The calculator wouldn't turn on when it arrived. I tried to charge it, but it would always die after after a few seconds. I opened it and found that the battery was leaking. The whole inner construction was very cheap and poorly made. Definitely no quality work. I owned many calculators. Never had one arriving with a dead battery. I guess there is a first time for everything. Didn't expect such a poor quality from Casio. ... show more
