Jumped ship today from flawless to Fab and already pleased I have. I haven't yet experienced any drops or buffers on any HD channels which were becoming a nuisance on flawless.
I shall come back next Monday the with a full review of fab, but so far so good. Even the support team have been very helpful and quick to reply. Could I request though that Discovery Science UK be added to UK documentaries soon. Thanks team Fab.
I'm in the exact same boat, changed yesterday and already a better experience altogether. I can actually sit an watch a program without constant buffering or stuttering.
