A few months ago I bought a new Vizio 2.1 model from Costco (Vizio SB3821-D6) and my dog has the remote on it nibbled high. I've searched many websites for a replacement remote. I quickly realized that since the model I bought was very new, spare parts were not yet available. After speaking to Vizio customer service, I learned that this remote, which was built for an older model, should work fine as a replacement. This old remote is missing a few extra buttons, but I didn't use those features anyway, so it suits me. Otherwise, it's basically the same, except the button layout is slightly different.
