Thank you for viewing! Please be sure to read my profile. ★ I am selling this because I am switching to a wireless keyboard. There were no problems when I used it. ★ Although it's not a gaming keyboard, it's a surprisingly rare keyboard with backlighting. ★ The lighting colors are green (as shown in the image), orange, and blue, and you can adjust the colors. ★ I have confirmed that text input is normal and that the 10-key pad also works correctly. ★ Connection is via USB. Thank you for your consideration. Connectivity: Wired
