Roughly the size of a beer can, the Nebula connects to devices via both Bluetooth and Wi-fi so it works pretty much anywhere. Its interface is simple to use, it can mirror screens of iOS or Android devices, and also runs Android 7.1 on its own. That means it can stream pretty much anything from a monthly service to a movie downloaded on your tablet. It lasts four hours per charge and, best of all, can cast picture up to 100 inches wide. The picture isn’t true HD, but we found it to be clear regardless. No, the Nebula isn’t a true television replacement. But it’s a great way to cast movies on a sheet for, say, a neighborhood summer film night, a showing of Frozen inside the pillow fort your kids created, or anywhere else (get creative). It’s versatile and it’s very, very fun. Buy Now $237
