I've moved over to Three mobile Broadband. Had it a week and no complaints.
I regularly stream 4K content and have experienced zero buffering.
It will however depend upon the coverage in your area and I imagine the number of devices that might be using it simultaneously.
I get all my online content via Freeview/FreeSat and the various players and by skipping around the free offers from other providers.
At £20/month for 24 months with 3 months free, my BBC licence fee and the occasional blu-ray disc I am more than happy with the cost.
If you read up the thread, there are also plenty of smaller, full fibre providers who might not yet appear on the comparison sites due to their limited coverage at present.
Enjoy the shop, there are alternatives out there.
