We ordered this remote in order to have a second one at a different location in the family room. The product received is exactly the same as the remote that came with the Sony 65x850D TV and works perfectly. Note that you can only configure/pair the voice control with the TV for one remote at a time. If you're replacing a lost or non-function remote, you register the remote's voice control through the menu system: press [Home] on the remote control, scroll down to [Settings], then [Voice Remote Control], then [Activate the 'MIC'], where 'MIC' is the microphone icon.
We ordered this remote on a holiday weekend and it was shipped promptly the first day that postal services were open, arriving in two days. The seller's service was fantastic.
