I don't have Plusnet TV, so cant say how it performs, but I personally would seriously consider it if it wasnt for the fact that for the past few months I haven't even had time to watch anything on my Netflix account. In fact I dont think Ive even had time to watch anything more than the news on my smart TV, so atm it would be a total waste of money.
But I did look into it and for my tastes the package is better and cheaper than Sky, Now etc. If things slack off then I certainly would be in the market to look at purchasing it. As I love documentaries, the only channel I really miss since jacking in Sky is Discovery, but I also liked Animal Planet, Sifi and History, so I was well chuffed that Plusnet offer these, and IMHO the price is decent.
The only other thing I'd have to look at is relaying the 20m of CAT5 that I ripped up last year as the Smart TV runs on wi-fi, but the PN youview box wont.
