Q: Didn't work. Tried it with 3 different phones and same result. The mic worked only when held in front from ear canal, that's not how they were advertised.

A: Bad review

Q: The characters in this book are so incredibly dumb. They say idiotic things, like when the girl is trying to get into the library she's on her phone and someone comes out of their room knocking at the house who they think it is, then proceeds to tell her not to. Just dumb stuff. I couldn't finish reading this...

A: Bad review

Q: I tried to install the battery correctly and it just wasn't that intuitive. On top of it, there is no light indicator, so you don't know if it's charging. If there's a charging symbol, then the battery shouldn't be dead. The only indicator here are LEDS at night time which change colors. It appears that, in this application, they put much less effort into creating an easier user experience for consumer.
