I have tried numerous shower radios and they all seem to be shockingly bad when it comes to reception. Despite the huge amount of radio stations in central london (where I lived until recently), I could barely pick any of them up on FM ... maybe Heart and the BBC nationals. It was enfuriating.
This Sony shower radio, however, picks up well on FM and AM. It's like a regular radio, not a novelty item like most shower models. In London I could pick up everything: 5Live, Radios 1 to 4, LBC FM and AM, Heart, Kiss, BBC London, XFM, Magic, Classic, Capital, Choice, the lot.
The presets are great. There are five preset buttons but you can store 15 channels (5 MW, 10 FM).
I've recently moved to Ipswich; my Sony radio came with me. There are fewer radio stations here and transmitters are further away. It picks up BBC Radio Suffolk, Town 102, Heart East Anglia, BBC Essex faintly and KISS East Anglia as well as the BBC nationals. Nothing outside the boundaries, just the staitions targeted at me as a dweller of this town.
On Medium wave: Despite the reports that it's aimed at the US market and hence a little off-centre when tuning in, it's really rather good. Bearing in mind all other shower radios are appalling, as discussed, this little issue is largely irrelevant. But I should note that it's irrelevant to me in Ipswich because it's a target broadcast area with a large population; in more rural areas you may have a problem on Medium Wave.
It's worth a punt. Really it is. And if you DO live in a rural area, and are keen to get BBC Radio Five Live on medium wave: buy it, get it delivered, tune it to as close to 909 or 693 as you can get, try it at night and during the day, and if you're happy with the reception then you're sorted. If not, send it back; being able to pick up Five Live is quite a big deal as it has rolling news and sport 24-hours a day.
One small thing ... the ariel is a very thin wire coming out of the back of the box. I have very recently broken it - it got jammed in a drawer and I pulled the radio not realising. The ariel very easily broke. This has reduced my ability to pick up FM but, as we all know, you don't need an external ariel for medium wave so it has not affected that. But a word of warning ... look after that trailing ariel. I might need to get a new one of these radios now.
Note: this is a good radio for visually impaired or blind users as it isn't menu-driven and so you don't need to see the screen. Once you've learnt to go up and down the bands and do a preset, you're there.
