But it's impossible to know whether those sats came from customers. 

Instead, try asking your customers to post pictures of your products in use and then link to those.

 i got my own bitaxe stand

 I may have to try that! Just bought my second Bitaxe and I will probably buy more. 

 i used to solder and build them on my own and sold them but its a very hard task so i dropped it and sell other stuff
