Most listings show the weight of a single Joy‑Con (including the left Joy‑Con) as 0.22 pounds per controller.
The Joy‑Con (left) connects wirelessly to the console via Bluetooth. Listings also note there are no wired connection ports on the controllers.
Many listings state the package includes Joy‑Con (L) and Joy‑Con (R) controllers and two black Joy‑Con wrist straps.
Listings describe the Joy‑Con (left) as having accelerometer and gyroscope sensors for motion control and HD Rumble (advanced vibration) built into the controller.
Two Joy‑Con can be used independently (one in each hand), combined on a Joy‑Con grip to act as a single controller, or attached to the console for handheld play to enable two‑player action.
Refurbished units are described as inspected, tested, cleaned, and fully functional; listings note they may show light signs of previous use and may be shipped in aftermarket packaging.
