A good little device that I use with my iPod Classic. It's simple and easy to use, and looks pleasant enough. It certainly eats up a lot of your iPod battery power (though not quite so much now iPod software updates seem to have solved a problem where the backlight flicked on every 10secs or so when the Robi was attached) but otherwise I've had no problems with it at all. There is a bit too much cable, which is the stiffer type and not so easy to squeeze into your pocket, but I suppose this is useful if you were carrying your iPod in your bag.
One thing to note: when I first started using it (without reading the instructions I confess), I was bypassing the headphones that come with it and using the Sennheiser ones I use for my iPod, but I found I was losing the DAB signal quite a lot. It seems the provided headphones contain an integrated antenna which I didn't realise at the time, and since switching back all has been fine.
