Query: Nice Sound Quality but Terrible Display

Two big problems with the time display: 1. The blue, backlit time display is impossible to read unless you put the clock at eye level in a darkened room. Any other angle, and any light (lamp, natural light from windows, etc) reflected off of the plastic display cover, renders it illegible. You can almost see this in the large product picture. I just bought two of these to use as sound machines for my toddler and newborn and I am willing to overlook flaw #1 but that brings me to #2. The backlit display is BRIGHT. I've used it in my own room the last two nights. I'm not a night light person and I can't sleep with the amount of ambient light this thing produces--I'm writing this review at 3:30 am. Researchers have found a strong link between night light use in children's bedrooms and myopia so I'm uncomfortable allowing these in my babies' bedrooms.
