I purchased a used phone off of eBay (motorola a630) that is known to have hardware problems.. they tend to break a lot. I received an email from square trade offering a 3 year full replacement warranty for $12... I'm not the type of guy to buy warranties for electronics but in this situation I think it might be wise. That said, I've never bought from them and I don't know how hard it would be to get my money back in a year... anyone know? Anyone have experiences with filing a claim? Thanks.
