After some 14 or so years of gentle, comparatively pleasant, awakenings, we were looking for a replacement for our old Natural Alarm Clock, a fairly crude electromechanical device that had finally become too erratic for its, or our, own good. The original manufacturer, OutsideIn, had morphed into Lumie, who no longer had an exact equivalent available, and do not - in any case - get rave reviews on the quality front.
The SRS100 works perfectly: a large clear display; an extremely well-designed and logical user interface that means the user manual can be rapidly consigned to the bottom of the drawer; very configurable; and, of course, you can use your own (very stylish) bedside lamp as the light source (as long as it's dimmable, so I'm afraid no energy-saving lightbulbs here). The SRS100 IS plastic, but feels sturdy and well-made. It is completely silent in operation i.e. no buzz or tick or hum. One word of warning, however: as of October '08, UK models were still lagging behind the spec available, and commented upon, in EU & US markets, where the SRS100 will handle 300W bulbs (currently only 100W in the UK), and the backlight can be turned off completely (current UK models will only reduce it to a faint, but quite visible, glow). The first of these is unlikely to be an issue but the second, depending on your sensitivity to such things, could be.
This aside, it's a really neat bit of kit which, for once, does exactly what's expected of it: highly recommended. The supplier, Bodykind, also provided very responsive, high quality customer service.
