Advertised by Microsoft as "the first-of-its-kind" console accessory, the brand-new Xbox Adaptive Controller can be already acquired from the Microsoft Stores and GameStop Online for US$99.99. This controller can connect multiple external devices to create a custom experience and was primarily designed for gamers with limited mobility.

Really impressed that Microsoft made this. The price is also very reasonable for what it is
I think the price is very good as well, especially since it's a rather niche product.
