I made a pruchase from them and got everything I ordered in good condition. Shipping took about 2 weeks but I got my product. I have been in contact with the seller many time and the new site is ran by the same people.
Did they offer to explain why they changed their domain name? I called GoDaddy to ask if they had shut down the domain, but they only said that it was no longer in operation and couldn't give me any details.
As you have surely seen from the tone of my other posts, I am extremely cautious, having been scammed once and vowing to only be scammed once. The fact that they changed domain names after three months in operation is a red flag to me.
