I assume you can trust us, because we are transparent about our company as much as possible.
Just theoretically, if something goes wrong and we will not provide our device nor money back, you can just go to the police and tell them: "they took my money". You have got all our data needed. In such case I'm not only need to give all the money back, but also i am going to jail.
This is not the same as: "I sent someone in Internet my money (in Bitcoins!!) and I dont know where this guy is, or how is his name, or anythig. Find him please!". This case in differerent , you know where to find us if somethig will go wrong.
But you are not a trusted supplier. A trusted supplier is someone like bitmaintech or spondoolies.
