I think the people at Pure decided to make the perfect bedside alarm clock radio. They probably listed all the functions their customers might want: a choice of DAB+ and FM radio; a choice of time display styles; brightness adjustment for the display to match either the ambient room lighting or the customer's preference; a neat little nightlight, again with adjustable brightness; up to ten different alarms, each operating at the chosen time and for the chosen days of the week; of course the alarm can wake you with FM or DAB+ radio or the buzzer, optionally with the nightlight coming on before the alarm, and with the alarm coming on either abruptly or gently fading in according to your preference; a backup battery so it doesn't forget the settings in a power outage; a user-configurable sleep function so you can drift off listening to the radio or one of the many built-in sounds (white noise, a crackling log fire, the sound of rain, a car ride, a tube train, and countless others); bluetooth pairing so you can listen to music from your smartphone on the Pure Moment's excellent (mono) speaker; and it's in a compact case that occupies little space on the bedside table (although there is a separate mains adapter to gather dust on the floor).Packing all of these functions into a clock with as few buttons as possible does mean that some controls serve several purposes depending upon context. E.G. The radio has a fairly usual knob to turn to adjust the radio volume but when setting the nightlight brightness or the display brightness the knob also does this; when choosing from a multi-choice list that same knob cycles through the options; this knob is also used if you opt to tune the FM radio manually, to set the alarm times and days, and for several other purposes. Some buttons behave differently depending upon whether they're briefly tapped or held down for 2 seconds. This can be confusing until you've learnt your way around.As other reviewers here have said, there's no comprehensive user manual. You get a Quick Start Guide that shows how to set up the clock, set the alarm, tune the radio channels, label favourite radio stations, and use all the major capabilities but it doesn't cover everything. After using the clock for a week I wondered if, instead of the radio or buzzer, could I set the alarm to wake me with birdsong which is one of the built-in sounds? The answer is yes you can but I don't think it's documented so I just experimented and found it. I recommend that you work through all the examples in the Quick Start Guide whether or not you need them. Then you'll understand what was in the mind of the designer and realise that most of these settings are arranged fairly intelligently. There are also some helpful tips and a few videos on the Pure Moment web pages if you get stuck.My conclusion is that this clock is very near perfect. If you want a clock that is high quality and versatile, and if you can afford it, buy this one. If you need alarms to wake you at different times on different days, this will do it. In an ideal world I would like the buttons on the top of the clock to be illuminated when the nightlight is switched on so that I could see which button to press in the middle of the night. Also, the radio antenna, which is just a length of wire hanging from the back, gives worse FM radio reception than a normal transistor radio with a telescopic aerial but thankfully in my home DAB radio offers clear reception on all the main stations. Finally there's a USB socket on the back of the radio but I can't find any mention of what it's for. It's not the increasingly standard USB-C so I haven't got a suitable connector to try plugging in my phone.
