confirmed scam. sent them 1 bitcoin for the 10 usb block erupters and nothing. to start with things were good had a response straight away thanks for your order kind regards, all good im thinking. Then I had another question for them so I asked and got a reply the following day, your package had been picked up and was on its way, this is getting even better im thinking what a service so I then asked another question, what delivery service do you use and do you have a tracking number if possible? NO RESPONCE and still no response after 5 or 6 more emails. so I thought I will be a little bit annoying and send them loads of emails just so I don't get missed in the inbox I sent around 80 of the same email and then bamm my inbox is going crazy with spam from every corner of the globe it would seem. so this also proves what I have read in other topics about this now is that there name was not bought out buy some spamming company it is them.
