UPDATE: December 2011 and the radio is still going strong on solar power alone after two-and-a-half years. Even though I have the option to charge from the mains, I've never had to. I'm impressed.
I've been put off buying a DAB radio because they've been either mains only, or had such poor battery life that they may as well have been mains only.
This SolarDAB is different of course, since it's powered entirely by light. Seems quite a breakthrough.
The radio itself is quite small and neat. It's not exactly beautiful, nor especially well-finished, but it seems solid enough and has a 'back to basics' charm about it. You might call it 'cute'. I think most of the colours it comes in are horrible, so I got the white one.
It's certainly practical: the grey ends (and therefore the feet) are made of non-slip rubberised plastic, as are the buttons and knobs. The arial points straight up or nothing, but it's one of the longest I've seen when you extend it. You can unscrew the arial and stow it in a slot on the back of the radio, which could be handy if you're taking it somewhere. Because the arial screws in, I suppose you could probably screw in an external arial if you needed to.
The display is simple and clear. The backlight comes on when you're pressing buttons on the radio and with the backlight on, the display is outstandingly clear. The backlight goes off after a few seconds to save power, but the display remains very readable.
The display can show the time.
Set up is extremely easy and took just a few moments. I didn't even extend the arial and got a full list of stations, all of which are crystal clear.
You have to charge the battery with the included 'eco friendly' mains adapter for 24 hours before you use it, so bear this in mind.
The sound is more than adequate for a small portable radio and goes quite loud. There are no tone controls but the balance is well judged and particularly good for spoken word stuff like Radio 4. There is a slight treble drop-off if the radio isn't pointing right at you though. But the best part of the DAB experience is the total lack of hiss.
I was surprised there wasn't a sleep function.
It's been pretty sunny since I bought it and the battery indicator hasn't dropped below fully charged so far even though I've listened to it quite a lot. The real test will come in the winter I suppose. I'm hoping that I won't have to think about the battery again for several years.
So, on the whole, this is a very likeable radio that works well and gives you the advantages of DAB without the permanently attached mains cable. Its solar technology, decent sound, excellent display and pleasant controls justify the relatively high price.
