I ordered a ZZP PCM 2 weeks ago and it arrived this past Wedensday. Went to put it in on Thursday and imagine that they sent me a bad one. Just UPS'd it back on Friday and calling them tomorrow to see if they can ship the new one out. I was planning on making the first track outing(with the new setup) this Friday, but it looks like my plans will probably not happen unless they ship it out tomorrow. First bad experience I have had with them after spending over $2000 in the past 4-5 years.
