No questions need to be asked, they are one of the very few companies who offer actual FTTH internet.
Their prices are also unbeatable, I paid £25 for 300 symmetric (though I got some sort of a deal), but even their regular prices at the time of writing are awesome.
The equipment they provide is also great, you are free to do almost anything, unlike with one of the major ISP dumbed down boxes.
Finally, I have had a single issue during my first year of usage, something affected a fibre link near me causing the connection to cut off occasionally. It was not a simple issue as usual tests, speedtest, showed normal results. They resolved it within 24 hours and I never had to wait long on the line when calling them.
I truly hope as they grow their service, support, etc will scale properly and then I am confident they will remain the best in the area.
