Thank you for viewing! TT This is an LED digital clock that I purchased new on Amazon a few months ago. It has a USB connection, a thermometer, and an alarm, making it very convenient. I am selling it because I am changing the style of my room TT. I have confirmed that it works and can be used without any problems.
