? for Echo Indigo owners, please

I thought it was $99 last time I checked. *shrug*

How compatible is it with your lap?

Any negatives to speak of?

Is it simple as putting it in and installing the drivers?

Does auto detect its driver every time you insert it?

I heard you have to reboot every time you remove it, correct?

Does it increase your sound level?

I would be using it for headphones only. Any feedback would be appreciated. Thank you.
