Overall, it is a great device that performs its core functions well. I specifically chose this model for its large numeric display and compact design; the 2.25” tall, bold LED numbers make it very easy to read. Here are a few specific details regarding the unit: The dimensions of the device measure 9” long (not 10” as listed), 3” tall, and 1.5” thick. I appreciate the indoor temperature and humidity display features. It also includes several customization options, such as the ability to set the colon to flash or remain constant and the option to cycle the display between both the time and date every few seconds. While the instructions are not written in the best English, they are relatively easy to follow. When you set the date, the clock automatically identifies the correct day of the week and handles DST adjustments. This clock comes with a 6-foot USB cable and a wall adapter. You can install two AAA batteries for memory backup, though please note these will not power the display or the alarm during a power outage. There are three standard brightness levels plus an "auto" setting. I have been using a fourth level labeled "SL," which seems to be the dimmest setting for nighttime while still automatically adjusting during daytime. I like that this clock keeps things simple by excluding radio or Bluetooth features. It is a reliable clock with two alarms that works exactly as expected.
