They are good at what they do - works out of the box, fast wireless, supports BT TV, supports dynamic DNS, no problems with port-forwarding, basic line stats.
But you can't change DNS, locked to BT, no error stats.
I would say a good basic router but no good if you expect any more than basic.
I totally agree, I haven't had that much of an issue apart from that one heat issue which was fixed by a factory reset, only gripe is the 14 day reboot and that lack of stats, I keep thinking about swapping over to our FRITZ!Box 3390 and keep this HH4 for when we have issues and need to do some tests.
Apart from that its not that bad, we have had a lot worse LOL
