So far so good.

It's an actual comparable replacement, but expensive

Before buying this, I bought 2 different replacement remotes on Amazon, one of which has the Samsung logo on it and is sold by the Samsung store on Amazon. Both had major issues. One would go unresponsive for like 10 seconds at a time. The other would fail to register button presses, or input them twice, and quickly got worn out to where it required excessive force to register a button press. This one was my third replacement attempt and finally it just works like the original remote. I'm removing a star because it was about $90 after shipping and everything, which is a crazy amount for a remote. But having tried two more reasonably-priced alternatives that failed me, I just bit the bullet.

Super quick shipping
