@DragDoll-
Warranty in US is 1 year (don't know about elsewhere).
Warranty claim instructions: https://support.roku.com/article/208757058
Note: On claims for remote controls, when they ask for serial numbers, the want the serial number from the DEVICE you are using the remote with, not the serial number of the remote. (I know, this makes no sense, but Roku is Roku.)
