And they specifically say it's a bitcoin node, not a miner, the miner is an addition.

Though they also certainly seem to have some issues that require some people to take action on the miner and be able to handle more than your average non-tech person can handle.

Probably due to the fact that they hacked up a 'new' miner for it for some unknown reason, even though they used an open source one before.
Not sure why they wanted to hide what's going on inside the miner.
And the system depends on not having the machine update itself properly.

i.e. just be wary of handing a non-technical person one of these as a miner.
