Yes had it from the Beginning, works OK with only a few Minor irritations.
Sometimes, and only sometimes, FastForward jumps in increments of 30 Sec. but can be rectified by going back to Planner and restarting (from where you stopped it) then it works OK.
Catch-up only goes back 1 Week via the Guide and can only be watch there and then, does not record for later watching.
If you are used to Sky then can be a little slow in acting, i.e. a small delay in showing Guide, etc. to the point that you sometimes push the button again and it cancels the operation.
But its an older Box so maybe these are now Fixed.
And it does what it supposed to do and is quite useful as a Back-Up to Sky bur maybe SKY Q will render this no longer Viable.
Not sure if you "Must" have TalkTalk Broadband, we have had Talktalk from almost Day1 and it works OK for us with Speeds in the 70Mb/s (Town).
