Every morning I wake up and say "Hey Google, play 680 news for 30 minutes." I don't have a physical radio in my house so before I was constantly casting Tune In Radio to the TV so this definitely makes things easier. I'll also ask for the traffic before I leave.
Lots of other small useful things have been helpful to me. For $40, it's worth it to me. I've also used it to make phone calls. The person receiving the calls were saying its not the best quality so I won't use it too often. My TV has Google Cast but for some reason not everything is loading up with the TV so thats a bit annoying but I could live with it.
