Not in sync with TV
Returned due to lip sync not being matched on TV. Probably better for car audio but not fot TV

Delayed audio, but otherwise works good.
Seems to work. Has about a 1/3 second delay so it does not work for audio that should be synced with video.

Solid works well zero hassle
Worked as expected older flat screen with no Bluetooth is now connected to my soundbar. Easy to hook up and has a strong signal. Also it’s plugged into the TV so I’m not sure what people are talking about in reference to battery power. Once it’s plugged in you’re good to go.

We like the USB that go BOOM!
Fixed my problem COMPLETELY! I had an older model TV have been using a fire stick, added an Amazon Sound Bar and it would NOT work untillllll I added this tiny little Bluetooth converter to the last available spot on the back of the tv and now, I’m watching movies from my bed with movie theatre sound, dancing while I’m getting ready for work and cooking up meals- it’s fantastic!!!

A subtle humming noise
The setup was easy and the device successfully paired my old Roku tv and JBL5 Bluetooth speaker. However there is a subtle humming when nothing is playing over. I will still use it as it is minimal when playing movies etc.
