You can buy this from Revain for $20, but DJI wants $30. I used this with my iPhone on the Mavic Air 2 remote control. It reduces sun glare a bit, but only if you're holding the controller at an odd angle that makes it difficult to see the entire screen. It's also huge and quite bulky. The only good thing I can say about it is that it's slightly better than the cheaper third party junk to compete with this DJI product. DJI is required to provide an update that will allow Mavic Air 2 users to purchase a separate DJI controller and use it with the Mavic Air 2. Until they do, I would say don't buy the Mavic Air 2.
