Review on 📲 4-Pack Silicone Case for Tile Mate (2020 & 2018) - Anti-Scratch Lightweight Protective Sleeve with Carabiner for Tile Mate Bluetooth Anti-Loss Device - Ultra Slim Skin for Full Body Shock Protection by Tim Knoepfle

I haven't tested whether or not they reduce the bluetooth range but even if they reduce it a bit I find it better than my tiles that are on my keys, bike etc. are damaged and do not work at all. They attach easily and seem fairly secure, but they definitely hold up with the key ring or carabiner that comes with each of the 4 cases. I think they're a bit pricey for what they are, but there weren't any better options at the time of purchase.
