Query: Nice Clock

I bought several of these clocks for my family members and they love it. No matter the time of day you can clearly see the time display. I'm not sure why some reviews state that the display is too bright in a dark room. I have mine set on low and it is not a problem. I've had to buy some rubber sticky pads to keep the clock from sliding when you touch the control buttons. The bottom of the clock tends to move easily when handling the clock. I've also noticed with some reviews that the clock does not stay in the desired viewing angle position. I'm referring to the adjustable viewing angle of the clock where it is adjustable from 0-90 degrees. Perhaps those people have a defective model. I've been able to adjust it to any angle and it stays in place.
