Hi everyone I want to share my review on the citizen cy 500 calculator. Generally studnets prefer calculators to most because they help them to solve the problems very easy even from a small integer to large ones. I had brought this calculator 2 years whch would be helpful for my entrance exams. But I found the calculations by this calculator gives me wrong output sometimes. Also sometimes it will take one value inspite of another one which I had typed. This calculator is also very slow in processing the information to get output. The display can be damaged very easily and if a small drops of water sprinkles on it , will not function properly.also the battery charging is very low and yiu need to change the batteries frequently. I found this calculator as less user friendly in my student life and donot prefer it
