Query: PLEASE DO NOT WASTE YOUR MONEY...

I have owned this calculator for 3 months and the dispay is no longer working properly. Parts of the numbers have "burned out" so only parts of the numbers show now. At first I thought it was the batteries. SO I bought replacements and that was NOT the problem. It is now completely useless. At $30, this calc is 10x's more than what a basic calc costs, so that is no excuse for such a poor quality product. PLEASE read the reviews - they all say the SAME thing. I was a fool for buying this. I hope this will help you.
