I’ve been doing these for years… they don’t work as intended for more than a year or two, and then become pretty unstable. Even the lady who created it went back to low-maintenance (as opposed to zero input) systems after a few years. Still with the dirt and all but not without water movement and stuff.
I don’t know this company but fiber came into my area (central WI) a few years ago and I couldn’t be happier.
Prior to that the infrastructure I was on for cable internet was old and would have frequent problems.
The brand new infrastructure is figuratively worth its weight in gold, imho, even if the company itself is just as crap and your price ends up the same.
Even better, the fiber cables run underground, so other than having them severed when digging, they won’t go out unless there is a major widespread outage. No random branch taking out your service in a wind storm or whatever nonsense.
