09 Nov 18 update. The battery is junk. The two AAA batteries I used last three weeks and three days. Pretty rubbish for a remote when normal remotes last 6 months to a year. Of course I understand that it uses Bluetooth instead of IR. For now it's pretty reliable for what I need. Unfortunately, battery life can be terrible. I've been using it for two weeks and the battery icon has already shrunk to two bars. Also the volume button doesn't work with my Sony TV and Sony Soundbar setup. Kind of confusing.
