This remote did not end up working with my Seiki SR4KP1 Blu-ray player. Testing showed that the remote was sending IR signals and that my player was receiving signals. But for whatever reason, they did not work together. ReplacementRemotes was very helpful and responsive to my queries and helped me by providing testing information. I ended up returning the remote for a refund. And that process was handled quickly and easily. I recommend ReplacementRemotes and will use them again.
