I was with plusnet for about 5 years. Initially we were very impressed with them and enjoyed decent speeds, with a good quality connection.
We left them about 4 months ago when they put their prices up - mostly as an excuse to get out of our contract.
First of all we noticed that we could no longer do multiple things on the connection (e.g. game while my wife watches Netflix).
Then films wouldn't stream and constantly buffered, as would Netflix. Netflix would often drop resolution and would even stop and buffer. Netflix says it only needs a 5mb connection for HD...
If we ran a speedtest, it would show it as having a typical speed for our connection (about 30-50mb). Interestingly, immediately after running a test, it would often (briefly) kick start our connection. We suspect they check the traffic for anything coming from a speed test server and prioritise it to make it appear like we were getting a better speed than we were. We obviously can't prove it though.
