Query: Outstanding product

I had this phone for 3 years. Everything about it was great except for the buttons. I think because they were made of a softer material, after a couple of years you really had to press hard to get some of the numbers to work. This is my only complaint with this phone. I wish they hadn't discontinued it, I am ready for a new one.
