I am not here to promote or blame anything and/or anyone.
I am just here to share my experience with FusionSilicon and my contact that sells me ASICS miners.
I will make the story short: I bought through my contact in China several X2 and X1 machines. I was a bit sceptic cause FusionSilicon is new on the market and asics owners knows how frustrating could be to deal with faulty asics or asics made with poor chips.
Out of the several X2 that I have bought I had 3 damageds hashboards. My contact contacted FusionSilicon about the problem and I was very pleased when they said to ship the boards back to replace them for free. Everything was organized by my contact VERY quickly. The whole process took less than 1 week by DHL. I had to pay the shipping to China but my contact in China decided to pay for the me costs of the DHL shipping to return the boards to me.
Faulty boards can happen. What was important for me was the customer support. I have to say, to be honest, that without the amazing support of my contact things would have probably been much longer.
I had a problem with an X1 machine. Firmware got corrupted or something. Red light. No boot. No nothing. Machine dead. no ip at all.
In just 12 hours my contact have been able to get ahold of FusionSilicon, get the image for the x1 and the procedure to restore it.
In 12 hours my machine was back online.
Bottom line: I am VERY pleased with the FusionSilicon customer service after sales and also with their machines.
And I am SUPER happy about my contact in China that, not only can find for me almost every asic for very good price with quick shipping, but she offers me an increadible support and helped me to fix every problem. Plus she is available almost 24/7 (she was giving me assitance during her honeymoon!!!!)
