Excellent fit!
Color: sky blue glow, Color: sky blue glow
After years of losing the remote we can finally find it! The case is a convenient way to attach the air tag but also makes the remote more ergonomically friendly. Easy to get on, fits well and hasn’t loosened up as some silicon cases can with several months of use.

Almost Perfect - More Glow Needed!
Color: green glow
Pretty good. Like the texture on the bottom of the remote, like a honeycomb. Makes the remote a lot easier to grip and subsequently find. One thing I’d change, I would make it more glow in the dark. It’s sort of glow in the dark, but I want a bright nuclear reaction of glow in the dark. This one just doesn’t have that power. For that, I give it 4 stars, but would buy again.

Good purchase
Color: Black
This case is very nice and adds needed heft to the remote control and is comfortable to hold. I’d opt for a lighter colored one or glow in the dark because it disappears if you set it face down on a dark surface. Lost it a few times until I realized I was doing that… otherwise I’m very happy with this and may even buy an AirTag to pop into the slot. Price is good too.
