The smart button, which is the main element in this television, does not synchronize in any way, the TV does not recognize it and constantly displays a connection failure message, it works as a simple remote control with the bare essentials

The function with the pointer on the television (I think it's called Magic Mouse) never worked. Hard buttons, we had to press with force. In the past few weeks, it would change channels on its own. I bought it around February, and finally now (June) I ordered an authentic one from Amazon. Money wasted. Completely.

Fully compatible with LG 55SM9010PLA and LG 50UM7450 that were tested. It was set up according to the instructions provided by LG.

It is like the original LG and works properly without any issues, and the important thing is that it is affordable in terms of its price, for 17 and something that I paid, it does its job perfectly fine

It does not display the indicator on the screen and voice recognition does not work - but it tells you that before you buy it. Connected immediately.
I deducted one star because every time you press the central wheel it says it is trying to connect to the phone and then fails (i.e. it displays a message in the upper corner, just annoying you for 3 seconds).
Otherwise, it works fine - for the money, it's just what you need.

The build quality is identical to that of the similar "authentic" one that costs three times the price currently, so I don't see a reason for someone to buy this one for 35+ euros. I bought it in a simple nylon packaging. The only button I didn't find compared to the regular square-shaped remote controls is the exit button, so you have to press home and choose from there. The feel of the buttons is very good and it doesn't miss any presses.

It mentions voice function as well as functions that resemble those of a mouse that exist on the original LG remote control which never worked. Some buttons are just decorative.
