Absolutely LOVE this remote, wish I had bought it years ago! I just put batteries in it and it worked immediately, no complicated pairing procedure required. We received the MR20GA model, packaged well, in an LG box. This is an actual LG remote, not an imitation. We have a 2018 LG 65" 4K LED UHD TV (65UK6500AUA) and this remote works great. It communicates with the TV using RF (radio frequency), not IR (infrared). This means you don't have to point it at the TV, you just need to be within 30' of the TV for it to work (I love that). It takes two AA batteries (not AAA), which were not included. It also has a mouse pointer function (similar to old Wii remotes) that's pretty handy. The fit and finish is exactly what you expect from LG. The scroll wheel has positive detents and scrolls smoothly, the four-way clicker buttons (around the scroll wheel) have a very tactile feel, but a very muted sound (not annoyingly loud like some of the cheap imitation remotes I've had). There's a very ergonomic index finger recess in the middle of the back of the remote which makes consistent hand placement a breeze. I love that I don't even have to look at the remote, I just pick it up and it's in the same position in my hand, every time. I can easily find the most commonly used buttons without having to look down at the remote. Having that little cut-out in the back makes a huge difference to me. The LG remote that came with our TV new was small, poorly designed, and cheap. It didn't have that recess, it was the same width, depth, contour, etc. the entire length of the remote. That (among many other design flaws) made for a terrible experience, as it was difficult to know where the remote was in my hand, I always had to look down at it. I realize this sounds a little petty, but once you've had a well-designed, ergonomic remote, you won't ever want to go back.
