I have heard good things, I just don't like the fact that they seem easy to lose being so small.
The latest iOS update (in beta right now) allows you to locate them (it tracks where they last were connected to the phone), and you can also play a loud sound from them to help locate individual missing AirPods. If you lose the whole case, you can't play a noise, but it will tell you the last place you had it near your phone. Not 100%, but pretty helpful.
I also don't think the idea that one could easily lose these should be a factor; people lose phones, wired earbuds, wallets, and passports, and none of those have generated headlines. I just think it's an easy "bash Apple" mindset that generates clicks, but is just stupid. Take care of your shit and this isn't a problem.
