As of March 10th 2015, I have an ongoing dispute which this person or entity. They have sold me units which were (2) SP20 Jacksons that were advertised as new by when received they were clearly previously used to mine for a long period of time. I have been and still am persistently asking that they kindly refund my money and take the used units back. They have stated that they are not open to my request, and they will not take or return my phone calls. Getting their phone number was not very easy to begin with. They say that all they can do is file an insurance claim with the shipping courier and replace one of the units which they say was damaged during shipping. They wish to file this claim despite the fact that the boxes arrived in flawless condition. They also have claimed that the units they sold me were not used, that they were only tested for a few hours at the most to make sure they are in working order before shipment, and otherwise in brand new condition. From the pictures I have provided it is very clear that the units were used at high load for weeks, if not months. For pictures and the public record of my case please refer to the following link: https://bitcointalk.org/index.php?topic=985885

BitcoinWare, I still have the units in the condition which you have sent them to me and I would still simply like a refund for them and for you to take them back.

Again: BE EXTREMEY CARFUL IF YOU ARE THINKING ABOUT PURCHASING FROM THIS PERSON OR COMPANY. They are NOT outright honest about their products.
