We love it for shopping lists.
We also have "her" in the kitchen. When we are fixing meals and see (say eggs) are running low simply say "Alexa, add eggs to the shopping list". She does and when we go to the store, that shopping list can be called up on the phone

. Our problem in the past is that we would make shopping lists and then leave them at home
We found that shopping lists can contain store names, so we have a Costco list, Lowes List and a default grocery store list.
Where we are, Alexa is not very accurate with weather forecasts.
I still worry about what Alexa hears during the day.. who else hears us all day long?!?!?
