Polar Heart Rate Monitor Problems?

Options
I have a Polar FT60 HRM. I have to send it back to Polar because it has a blank spot on the display. It's not even 1 1/2 years old, and I had this happen.

Has this happened to anyone else? Did you send it in to be fixed? Was Polar good to deal with on the issues you've had with yours?

Thanks in advance for your help.
