This was the perfect size for my desk and the information is easy to read at a glance (including time, temp, humidity, date/day info). I don't use the alarm clock feature, so I can't comment on that part of it, but it seems to be exactly what I was expecting and wanted. It was pretty easy to set up and seems to be working perfectly. You have to push the top button to get the back-lit display and it only stays on for a few seconds. However, in my office lighting (overhead fluorescent lights) it is still easy to read. Not sure how easy it would be to see across a room, but for that purpose you should probably purchase a wall sized clock or something bigger than this.
