Knocki brings any surface to life. This original edition Knocki works as beautifully as it looks.

The Knocki device — the hockey puck-sized gizmo you’ll find in this month’s box — can go anywhere you need it, using its included mounting bracket. It connects to your devices through Wi-Fi, eliminating the need to program each individual device. And it also calibrates to the environment in which it’s placed so it can distinguish between a tap meant for the Knocki and a glass being placed on a table or an elbow bumping the wall. In a word, this device is smart.
