So my kids and dh are bugging me to get an Alexa for the house, I've looked on amazon for the reviews (obviously all positive as it's an amazon product) and I've tried to read all the actions it offers but still not getting what it really does, I like the sound of the intercom system in the house (happy to purchase two if they are good for this) we're not a particularly busy holdhouse or a high tech one, are they worth it and what else can I do with it? TIA ladies. X
