Regain immediate control of five top TV brands – no programming required! The patent-pending UltraPro One-Touch Replacement Remote works in place of original TV remotes for Samsung, Sony, LG, Vizio and Roku TVs. Its preprogrammed TV device buttons let you skip the programming and jump straight to your favorite shows. Simply insert two AAA batteries, then press the TV device button for your TV's brand – that's it! Each button is already set to operate that brand's TV. Whether you have any or all of these TVs throughout your home, this remote can control them all, making it the best replacement remote and a great spare remote to always have on hand. While the AUX button comes preprogrammed for use with Roku boxes, it is programmable for use with another A/V device, such as a soundbar, Blu-ray/DVD player and more. In fact, this universal remote control is compatible for use with all major brands and can operate thousands of audio and video devices. Additionally, its master volume control feature, once activated, lets you adjust the audio no matter which device is being used. Access unlimited entertainment – TV to TV and room to room with the UltraPro One-Touch Replacement Remote.
