### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works
  

*by J***M on Reviewed in the United States on October 24, 2023*

Bought a pre-owned Vizio soundbar with subwoofer and it didn't come with a remote. Picked this one up and boom, it worked without a need to program it. I needed it to switch to the optical setting on the soundbar, plus, I feel like it's always nice to keep the original remote to any device even if another remote handles the bulk of the work.

The replacement remote was an exact replacement for my worn out original.  It worked perfectly without any setup or programming.  And the price was super!
