Looking for a fun gadget to gift your techie friend this holiday season? It’s time you jumped aboard the Snapchat Spectacle bandwagon, for it’s a craze that’s taking the world by storm. Snapchat Spectacles might look like ordinary sunglasses but in actuality, they are camera-enabled to record videos and let you upload directly to Snapchat. Because you’re not waving a camera or a smartphone in anybody’s face, the Spectacles allow you to capture precious moments without being intrusive or obvious. In fact, the usefulness of the gadget goes much beyond the realm of entertainment, for it was used recently by a UK teaching surgeon to livestream an operation to students. While it’s not easy to get your hands on the Spectacles (people have reported waiting in queue for up to 10 hours!), they’re definitely worth the hassle.
