This $20 accessory is the best thing I've purchased for my ROG Ally
I hate, hate, hate fingerprints.
I use my ROG Ally X for more than just gaming, and out of the current crop of PC gaming handhelds, it's by far my favorite. I've upgraded the internal storage for more space, use a bunch of other accessories to get the best experience, and am never far from a fast-charging GaN USB-C charger or battery pack. But there's one thing that really annoys me, and I spent the easiest $20 of my life fixing it.
