Oh well, I give it a fair try, but 90 minutes in silence, with "opening device" on the screen finally convinced me, and Halfords were happy to give me a refund this morning.
What a pity, it's a great idea: What on earth have they been doing since they announced it last Autumn? I wouldn't even call it ready for beta testing, and then you have a fascia that drops off frequently with the volume knob rolling somewhere inaccesible.
I'd take some convincing that they'll ever fix it, and anyway I'd want to be sure that it was a different batch with the fascia fixed: I wish I'd read their forum on the R&B, I'd never have bought it.
