And when you're out of the house, the Dot can tell detect any irregularities (broken glass, smoke alarms, etc.) and communicate them to you so you always know what's going on at home.
Promising reviews: "I bought this product because I wanted to upgrade, and the new generation is amazing! I love how that speaker is a sphere, so the audio is better. Overall, I recommend the newer 4th generation Alexa, she’s super convenient." —Litzy
"Since connecting my new Echo Dot, I continue to be surprised and pleased. I can tell it to turn on my office lamp before I enter my office. With my phone contacts now synched, I can have it call people and have conversations through the Echo. And now that my printer and Echo are connected, I can even ask my printer to make copies of certain things. I was so pleased with the Echo Dot I just bought four for Christmas gifts. I continue to look for many more ways to make this device useful. You will not be disappointed!!" —PeterCW
