Mine has been a workhorse. I have the 401. I hardly clean it. I reset it once in a while when I notice it's not hashing. It once configured, you can leave it. I still like looking at the control page when you log into it. A single ASIC doing magic.

How often do you need to reset it? I’m wondering if it’s worth the hassle of setting up a bunch of them all over the place. Like hundreds of them across the city. If I gotta run around and physically maintain them it’s probably not worth the effort
They are stable. Like set it and forget it. I haven't experienced any issues with mine for a very long time. Updates they made along the way solved most of the problems they had in the early days.
