This is the first generally available product that supports the new (December 2009 in the London and North-west areas) Freeview HD broadcast standard.
So is it any good? Well, it depends what you bought it for.
If (as for most people), you just want to watch the new Freeview HD broadcasts, then yes, it is very good.
If, on the other hand, you are expecting much from some of the product's other features, then I'm afraid you are going to be disappointed.
First, the good points:
Setting the box up was a complete doddle - just hook it up to your convetional aerial cable (you'll need an additional cable if you want to keep your TV connected as well) and to your HD-ready TV via the (included) HDMI cable, power-up and the set will tune into all the conventional and the new HD channels in fairly short-order.
The picture quality on the two available HD channels (BBC and ITV1 - Channel 4 is allegedly starting its own service in the near future) was excellent on my HD-Ready (but not 'Full HD' in my case) Panasonic LCD TV, although as others have pointed out, you do need good HD source material for this to really work.
The BBC appears to be producing most of its current output in HD (ITV appears to be doing so a lot less of the time) and watching the winter olympics, the six nations rugby and the Carling cup final in HD has been a revalation.
The box also seems to 'up-scale' output from the other standard definition channels to match up with the best resolution available on your TV, resulting in a noticeably better picture (less artifacts) for these channels than from the equivalent output from my TV's built in Freeview receiver.
The TV user interface on the Humax is largely intuitive - the TV guide, programme information etc. are all clearly presented and the remote control is of good quality, albeit rather large.
However, the Humax does not perform as well as this in all areas:
The maximum audio output level on the BBC HD channel especially is much lower than that from other sources used with my TV (the built-in tuner or a Sky box, for example), resulting in the annoyance of having to continually alter the TV volume level when switching between sources.
Also, no matter how hard I tried, I could not set-up the remote to control my fairly standard Panasonic TV (whereas I had no such problems in programming the Sky remote to do this), so that means yet another remote on the coffee table!
The Humax also comes with an Ethernet connection and the included blurb makes the boast of it being fully 'DNLA compliant'.
Unfortunately, the inteface and controls for accessing other DNLA devices (I have a compliant Network drive, NAS) are simply appalling - completely non-intuitive and very 'buggy'.
When you finally get down through all the levels and manage to access something, it really isn't worth the bother - the only video files it can read are 'DiVx' (supposedly a sub-set of AVI, but none of my AVI files work), I couldn't create a playlist for the audio files - you only seem to be able to sequentially play the files within a folder (normally an album) and the slide show facility for photos was like something out of the 1970's, with "Processing" flashing up on the screen between photos (very retro!).
The USB storage option is also only of limited use, as it is for playback only - there is no means of recording to the USB storage device.
It also seems that the aerial output from the box is turned-off when the box is in standby (whereas that on a Sky box or VCR, for example, would still be active), meaning that if you rely on this for the aerial input to your TV then it will 'die' when the Humax goes into standby - I guess there may be an option to change this in the command menu, but I haven't looked into this yet - I am just using a parallel aerial feed instead.
So in conclusion, the Humax HD-Fox T2 is a great way of getting HD broadcasts without investing in any additional hardware (e.g. a satellite dish for Freesat) or paying a subscription (e.g. Sky HD, Virgin Media etc.), providing you have a conventional aerial capable of receiving Freeview broadcasts and an HD-ready TV.
However, I certainly wouldn't rely on any of the 'peripheral' features of this product being of much use and you should also bear in mind that there will be other Freeview HD STBs available in the very near future, along with PVRs (doubtless Humax will release one themselves, as they are something of a specialist in this area) and fully-integrated Freeview HD TVs.
