Nintendo's new retro wireless SNES gamepad is available to purchase for Nintendo Switch Online members. If you're already paying the $20 a year subscription fee then you are eligible to purchase the wireless controller for $29.99.
Unfortunately, the controller is only available to those who have signed up for Switch's online membership. A large part of the controller's appeal is retro simplicity, but this feature also renders it ineffective for playing more complex contemporary titles.
The controller can be recharged using the included USB cable or a Nintendo Switch AC adapter. It is temporarily out of stock for now, but stay tuned for a restock.
