I've had aquiss for a year now, I've not had a single fault. Their website has instructions for opensense (pfsense) and these worked right away.
When there has been an outage or an issue with the potential to cause outage they let me know, but I've been at work when this has happened.
It would be nicer if it was cheaper, but stuck on open reach/BT infrastructure I can't fault them.
You can actually talk with them as well.
