I just got through doing a painless return through Amazon. I first started by contacting the vendor direct for an expedited replacement of a bad (new) part. That was a mistake. 2 min on the phone with Amazon, refund on the way... If you get a bad part through Amazon, dont try to get a replacement, just return it and order from another vendor, Amazon will usually provide (at least) a half dozen for the same part. That way, you wont have to wait for the turn around, and you'll get it in about two days.
