models XR11 v2-UTU and XR11 v3-UTU remote controls. these can be programmed to control a variety of TVs and other systems at www.xfinity.com/support/remotes. one of the remotes includes batteries.
I've had varying success with TCL and Samsung TVs. these remotes will successfully control the TV's power, volume and channels but not all of the other features work for some TV models.
