I purchased a cylinder and head. Zachary Penick shipped the jug with no protection for it. The cast liner ears broke off. He said he would ship me another cylinder. After lie after lie after lie, I finally opened up a Paypal dispute and then a claim. We are in that process right now. This has been going on since September.
Now it looks like if this is the same person as in the news story, he has a history with the law also.
PAYPAL users - you might want to think twice about sending money as a gift. I think you forfeit your buyer protection.
