This device is very smart - it gives accurate and concise answers much more frequently than Siri, which we've used for some time. We have three of them in different parts of the house. It has a broadcast feature that we use to let everyone know dinner is ready, etc. It can make phone calls, play our music, and control various devices. It has a todo list, hooks up to Pandora, translates words (the kids take Spanish in school). We use timers to enforce sharing of our Nintendo between the kids. We also use alarms. The kids played some games with it and used it to "call Santa". Fun stuff. I'm looking forward to using it for light bulbs and hooking it up to Chromecast. This was one of the best things we bought during the holidays. We bought several for $29 and gave them to relatives. Everyone was really happy to get one. The volume can be high for a small device. We find we have to turn it down ("Hey Google, turn the volume down 50%).
