As a former Technobit customer, their customer service was terrible from the start. Their S-hash boards were well built, but also failed to mention that power supplies weren't included on their poorly designed website.

I really wanted to have trust in them to buy more products but the more I troved this forum, the more late, or missing miners threads kept popping up.

Needless to say, I'm not surprised in the slightest bit.

But this type of behavior seems to be the norm in the Bitcoin mining industry, unfortunately, with a small handful of exceptions. Its sad what greed does to people.
