These machines are not meant to last just a month, but to generate value over a longer horizon a goal only accomplished by building reliable, high quality products.
If Hashfast REALLY felt that way, it would guarantee its hardware for a more reasonable timeframe, like 180 days. It's obvious that the ROI of your products will be either thin, or nonexistant, particularly for those who paid you with BTC. Don't add insult to injury. Man up and increase the warranty period, or stop making ridiculous statements. kthx.
