So your grad is heading off to college, or their first apartment. The first thing you'll want to get them is a digital assistant. Alexa can help them manage their schedule, plus the Echo's speaker is great for music and games.
If the kid is Team Google, then a Google Home might be a better option than the Echo. If you get them the right Chromecast devices, your grad will even be able to cast music and videos to other speakers and TVs around their room.
Of course, whether they're heading to college or to their first job, life isn't just about having the coolest room. Step 1 for classes or work: coffee. The Braun BrewSense is a great machine for those new to coffee. It's affordable, compact and reliable.
If they want something that's a little less obtrusive than a robot vacuum, a flood detector might help keep them from waking up knee-deep in water after a burst pipe. The D-Link Wi-Fi Water Sensor doesn't need batteries, and it'll send push notifications in the case of floods.
Your grad is growing up, and while taking early professional steps is important, so is having a little fun. Fizzics is a clever beer machine that lends bottled beverages the mouthfeel of their tapped counterparts.
