Works perfectly with my Pioneer SP-SB23W sound bar and subwoofer. Out of the box, battery in remote, works instantly, no setup required. This remote also looks exactly like the remote for my Roku T.V. which I find funny. This one does require batteries although; my Roku remote is rechargeable with a USB Type-C and has extra buttons and features. Kinda sucks having to have two separate remotes for my TV but this is an older sound bar.
Overall I am pleased with the shipping time and the quality of the product! Would recommend
