We have B4RN for almost six years now. Admittedly, at first, I was skeptics, but after checking my speed soon after going live, not any more!! It really is a gig! The cons you mention are true, but are so relatively unimportant as to be hardly worth mentioning. Yes you lose internet with a power cut but nearly everything else goes off also! If you can’t manage a few hours without electricity...... I say no more. In this age of mobiles not having a landline does not present any problems. As regards digging your own dusting, I was late 60s with, unbeknown to me, stage 4 lung cancer when I did mine!!
I think I have only had 2 outages in 6 years and both were speedily and efficiently resolved.
Price wise, for B4RN and Vonage, I am paying less now that I did 6 years ago to BT for a miserable 1mbps( on a good day)!
All in all, if anyone is offered B4RN and doesn’t take it, I shake my head sadly.
A brilliant, truly local, company that gets a 10 from Len!!
