How useful you find this will depend very much on your expectations and application. At this price-point the feature-set is impressive - but also it's weakness.
Including a Freeview decoder in a portable device is always going to be problematic. For myself, I never really expected to receive digital channels using the portable aerial. Although transmission signals in my area are good, I live on the 1st floor of a block of flats and there's a lot of concrete and brick between me and Crystal Palace.
Using a feed from the rooftop aerial, reception is OK. Again, this is challenged as the aerial feed is shared. Reception on the busier Freeview multiplexes with less bandwidth (e.g. all the Five channels) is variable. This also reveals the shortcomings of the digital decoder in this unit. Using the same feed, the Freeview decoder built into my Sony DVD recorder has no difficulty receiving and displaying all channels. The August unit however struggles and the error correction is not as robust.
There is a very useful signal strength and quality indicator that can be accessed by pressing the "Display" button on the remote. This can help with identifying an optimising any problems with aerial leads and connections that are limiting performance. Adding a signal amplifier to the circuit improved things marginally - but not hugely.
It's a similar story for the digital radio channels. They can suffer from drop-out.
Bottom line though is that if you're not living in the shadow of your regional transmitter, don't expect to receive Freeview using the portable aerial. And as with all other Freeview units I've used, you need a decent clean feed from a rooftop aerial to receive all channels reliably.
These not unexpected issues aside, other aspects of the unit offer excellent value for money.
The screen quality, brightness and clarity are surprisingly good with all the necessary menu choices to optimise the picture. Ultimately, colour accuracy and resolution are restricted - but at £200 it can never hope to compare to what was a £900 CRT TV I have as a reference.
The electonic programme guide (EPG) is OK - but not great. Frustratingly, as soon as you scroll through the guide to see what's on the other channels, the in-picture display changes channel to whatever you've highlighted - which take a second or two. So you can't quickly scan through the EPG to see what's on.
Sound from the onboard speakers is acceptable and not overly tinny despite the restrictions on size. It's certainly capable of delivering loud enough volume for all domestic applications.
The DVD player is capable but despite the list of compatibility in the specifications the one type it refuses to play are DVDs authored on my DVD recorder. I've played these in other machines no problem so this is a disappointment.
I bought the version with the rechargable battery but haven't tried this yet.
Overall, a great set of features combined in a practical (if not very sexy) unit for not a lot of cash.
