Review on Enhanced Replacement TV Remote for Insignia or Toshiba Fire/Smart TV 📺 Edition 49LF421U19 50LF621U19 55LF621U19 TF-43A810U21 NS-24DF310NA21 NS-39DF310NA21 NS-39DF510NA19 NS-43DF710NA19 [No Voice Search] by Mike Lunde

Looks good, smells good, goes well with my TV. It doesn't "feel" like my old remote (I find it lighter and cheaper...) but I didn't care. a little red LED on the top showing it's working... I like it - the old remote didn't have that. (Press the button and the LED lights up.) It paired fine, but otherwise it doesn't work with my TV. To be clear, the buttons work - you press them and everything happens.... However, the remote happily changes the volume and channels on its own. When these random things look at the remote, I see the red LED blinking - Note: I get the same (LED) reading when I press the buttons on the remote. All in all, the crazy things my TV is doing are obviously caused by my new remote control. When I removed the batteries, my TV worked normally again. I thought I was crazy and my TV was dying until I bought a "real" remote control for the Fireman TV at a big (blue and yellow) store down the street. My TV is fine. Blame that remote. I'm not upset - this remote just doesn't work with my TV - your experience may vary. Much luck.
