Although there are some negative reviews here, I for one am happy with the Siesta Mi. I didn't expect huge, room-filling sound, and I knew that my bedside table was below my eyeline: so the viewing angle wouldn't trouble me either.
And I have not been disappointed. Yes, of course it would be nice to be able to set the volume for when you go to sleep, and have it different when you wake up. And of course it would be nice if the digits in the display were slightly fatter and not so close together. I suppose a remote control and a teasmaid would have been nice too: but a DAB alarm clock for under £40, with dual alarms, auto time-setting, in a very pleasantly designed, sensibly laid-out and nicely finished unit, is a bargain in anyone's book.
I unpacked it, plugged it in, and left it for two minutes. Once it had stopped autotuning (and found 50+ stations with only the wire aerial), I glanced at the one-page manual, preset my favourite 5 stations (it can hold up to 16), set my alarm, and started listening.
So I am very pleased. I must agree that, if you do have to look up at the unit (i.e. your bedside table is above your head), then you won't be able to see anything on the screen. However, this isn't a problem for me and so I can give it 5 stars without thinking.
