Purchased for a pre-teen boy. He loves to customize the colors both of the numbers and on the bar below. Additionally, I like that the lights can be dimmed down at bedtime. Finally, the alarm has 3 different noise levels and 2 alarms making the clock very customizable.

Enough Colors To Make Me Happy

Great, but you do need an an adapter for your power cord, as it's a USB, and won't plug into a standard NEMA outlet. I was lucky to have an extra one from my phone charger. It only requires two AAA batteries, not two, that are required in case of a power failure. It was a little tricky to set. It requires input for year, month, and date, before getting to the hour and the minutes. I found it a bit confusing, and even though I tried repeating all the steps after setting the time, the two dots between the hour and the minutes keeps on flashing by the second. Yes, they do tell you how to make it stop in the instructions, but that doesn't work. There are many colorful choices to pick and choose from. You will never get bored with the options. The numerals are big and bold. The dimmer makes a difference for my personal taste. I still can't figure out how to turn off the ambient light bar at the bottom, but it does turn off when you dim the numerals completely, at bedtime. I don't use 1 or 2 alarms, so I didn't mess with that feature. I spent too much time comparing all the features from the selection of this type of clock on the Walmart.com site, but I chose this one because I liked its options, and the great sale price.

fun, customizable clock

It is fun and easy to change the color %26 brightness. The light can be dimmed for comfortable sleeping and there is a cool option to set the 2 alarms for different days of the week/weekend. The settings are easy to understand and use.
