HORRIBLE CALCULATOR *DOESNT WORK*
Oh my god! Don’t buy this calculator, this calculator is horrible! I brought one and when I opened it, it worked normally, but after 2 days, it suddenly stopped working. At first, I thought it was because it doesn’t have battery, so I left it in the sun for like 5 hours. But it still didn’t work, I replaced the item and the SAME THING HAPPENED, except this time, it arrived not working. This calculator only works under direct bright light, once u leave the bright light, the calculator turns off. **THIS CALCULATOR IS DEFINITELY NOT RECOMMENDED FOR SCHOOL USE** At school, the ceiling light is too far away from your calculator, so it won’t turn on or work. DONT BUY THIS HORRIBLE CALCULATOR!!
