Another week has passed and no payments arrive on the Z11. Now I am convinced that it will never come again. Unfortunately I will not get back my invested $. I believe that even asking for an exchange with Z15 the answer will be no. Now I don't want to pass as a racist, but it is a typical Chinese product, ineffective, incorrect, without help. My latest investment with Chinese. They sell poor quality products with promises of high income and then they are unreliable.
On facebook they boast that you have AUM 10 billion dollars, so why don't they help who was penalized by their minig farm with fair trade? The days of blackouts soon surpass those where their miners worked.
I apologize to other bitcointalk users for my outburst, but now after a long time it is necessary.
