They're getting better. It's a little reminiscent of Android, actually, which wasn't really solid until KitKat. For example, I have a microsoft bluetooth mouse that is utterly painless & two AA batteries last for something like a year working full time. Also have a pair of Jabra 65t, pairing is annoying and on rare occasions it hiccups, but 97% of the time they are excellent. I had owned BT mice & headphones previously, and they have never been better than today.
