In the LG 37'' 2009 model, I did not encounter any connectivity issues or anything else. It even picks up signals if you have it pointed elsewhere and not at the television.

It does what it says, but the smart button does not open the correct window and some of the buttons are mixed up compared to the (correct) original.
The worst part is that when trying to move the arrow right, left, etc. in YouTube or a movie to fast forward or rewind, it literally DRAGS!!!
Everything else is good.
P.S.: It's been dropped 10 times since February 7th, 2020, and it hasn't had any issues! It's even handled by children's hands! I'll give it one more star ...
