I bought a couple of miners in 2017 and now have some coupon codes which I dont have any use for:

8x 200$
8x 125$

Please pm me if interested. I consider all reasonable offers. Payment in BTC, LTC, ETH

This is a legit offer and not a scam. I can provide proof in quick a skype call if needed.

Just wanted to thank you for this awesome firmware patch. I had lots of issues with the original firmware because I got lots of HW errors and the miners started randomly stall and reboot which was really annoying due to the full fan speed up each time. This always happened in the middle of the night and my neighbours were already complaining. I now save money with the lower power consumption and get way more uptime due to the advanced firmware. The 1.5 dev fee is well worth it I can get 20-30% better performance. One feature I would love for the future would be an automatic night/day mode where the frequency, voltage and fan speed changes accordingly to the time. So I can mine at a maximum profit during the day and at low noise during the night. THANKS!
