Query: Quick and easy with good ergonomics

I plugged it in and it knew the time. It has an installed lithium battery so a power drop won't cause it to flash 12:00 at you. You will have to adjust a single setting if you are not on East Coast time. Setting the alarm is as easy as toggling left or right to increase or decrease the time. It is very quick and zooms through until you let off. It is very intuitively designed and fast to change the alarm time.I purchased this for eleven bucks delivered through Amazon Prime. This is an incredible bargain for a very well thought out alarm clock. If you want practical, this is it. If you are looking for a dazzling home audio experience at 6:00 in the morning, you need to keep looking.
