This mining equipment has no reviews yet. It means less resets, antminer maintenance, less downtime, less mining time wasted on repairs and replacements, and less aggravation in general. The T9 was sold with a day warranty, which is obviously twice as good. That said; the next batch of S9s will also feature this day warranty.
