Digital Desk Clock, Wood Grain, Brown Alarm Clock 3-Level LED Brightness Adjustment USB Powered (or 4 AAA Batteries) Thermometer I loved the stylish design, but I'm selling it because I bought a new clock. USB cable included. There is no instruction manual, but you can find similar products online, and you can use those to set it up. I used it with batteries, but it didn't seem to power it very well. I think using USB power is better. Please be aware of this when purchasing. Shipping will be via either Yu-Yu Mercari Bin or Kurakara Mercari Bin. (Shipping method may change without notice) Thank you.
