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.
