Worthless. Unless you are customer of theirs don't bother calling. They have lousy phone etiquette. I wanted a repair piece for my current phone, the person who answered didn't want to continue our conversation because my phone is from a different carrier. I need this phone repaired, I don't care who has the part, I need a phone for when I go out of town tomorrow. In case you are wondering this elusive piece, is the tracball for a Blackberry. Simple to replace, but I am having difficulty finding one. .
