Review on Enhanced XRT500 Backlit QWERTY Keyboard Remote for VIZIO M471i-A2 M501D M501DA2 M501D-A2 M501dA2R M501d-A2R M321i-A2 M401i-A3 501i-A2 M551dA2 M551d-A2 M551dA2R M551d-A2R M551DAR2 M551D-AR2 by Ann Thompson

We bought a universal remote back when we still had a cable. Years went by but we continued to use the universal remote, even though some key functions didn't work on our Vizio TV. Eventually some buttons started failing, so I remembered and searched for the original Vizio remote. It didn't work at all and we were left with a bulky keyboard. I ordered this remote control and it worked right away (after putting the batteries in). Nothing set, nothing. Each button works as advertised. Also, it has a keyboard on the back so the full size can be put back in the closet. Good.
