Query: Disappointing - Display stopped working in less than a month

The sounds are all a lot of fun - waterfall, rainforest, beach etc. The beach seagull calls repeat too quickly. The sound loop is a little short.The radio sound is not very clear.The overhead projection is a little too bright for sleeping, upside down on the ceiling and a little fuzzy. I worry about having to change the bulb in it.The really bad part was that the display stopped working correctly in less than a month - the last digit is now permanently displaying a number 8. So it's impossible to tell if the time is 12:00, 12:01 or 12:09. You can be off by 9, almost 10 minutes.Very light-weight and flimsy construction. Does not feel solid.
