This small silicone "case" fits my Tile perfectly, a 2020 Tile Mate, and helps it stand out from my other Tiles, which I wanted since it makes it easier to distinguish otherwise similar keys (which I started using both of my Tiles for--I could have just bought a different colored Tile in the first place, but they were harder to find at the time and I didn't really have a use for another one or a desire to stop using a perfectly good one now). There is a cutout for the little speaker holes on the Tile, so the little chime comes through just as strong with this on as with it off.Not much else to say, other than that it's held up fine through a few putting-ons and taking-offs, as well as months of use in my pocket and bag with other items. Happy to have discovered that things like this exist, and it's a nice alternative to different colored Tiles even if you don't have need for a case in and of itself!
