Do not purchase without paypal. You will thank to me later on. I received the used miners in few days but all miners were in bad condition. First there were so much dusty, bird $#*! and other materials on them. I clean up very gently but that didn't enough. On 3rd day after start runing the miners, I shutted down immediately. There were very weird bad noise looks like it's going to to be died and I've checked the plug and socket were burned. I think the seller stopped using paypal because of complaints. He doesn't like complaints but he have to think about that before start selling faulty item in brand new price. My suggestion to all, do not buy second hand from abroad without paypal. Stay away. Invest your money in different bussines. See the pictures. All miners in same bad condition. I only using one of them because rest of them doesn't work. I need to change fans because of weird noise like scream.
