HF3519/01 - good product, but very expensive
It's intuitive to use, which I hadn't expected from the negative reviews. In fact, the only functions I wouldn't have figured out without the instructions were how to demo the alarm/s, which buttons turn the alarm off whilst leaving it set for the next day (for me, tapping Menu is easiest - if the display is off, it lights up again when your hand gets near); and toggling the feedback beep on or off. Everything else was easy to figure out straight out of the box.
