I bought a DK03 December 15,2022. While the keyboard never worked well for either laptop (maybe every 5th keystroke came through), it did work well with my Samsung TV so I kept it for that. The mouse, however, was a joy, and the fact that it had 2 Bluetooth channels so it could pair up with the keyboard on the TV and still work with my laptop was great. But now the scroll wheel doesn't work, which reading the forums seems to be a common problem. Now I'm regretting not having returned the set back in December, and my return window closed last week. Is their any type of support?
