I've had one for 3 years or so and use it between the van and the Zed. Have it on all the time in the van and in most areas the reception is good, much better than it used to be as DAB spreads. One word of warning though, the screen aerials are not good and on both the van and the Zed I use an external aerial, glass mount on the Zed. This site is worth a look as it's come quite a way since the Pure DAB.

I'll see if I can find a picture of the aerial on the Zed Lincolnbaggie had one and it worked well for him too
