Wish all silicone cases were made like this
Color: Black
Deserves a good review. Made well, fits in your hand, stylish, textured so it doesn’t slide down into the couch. Not the cheap thin silicone cases. As spoken, made well! No way to be disappointed here, buy on with confidence

Fits perfectly! Doesn’t glow though
Color: green-glow
This fits the correct remote perfectly. I liked it gives it a little bit of weight and it seems durable. I gave it four stars just because it doesn’t glow and I picked the one that was supposed to glow. Just an FYI they don’t glow, but they are good covers.

Good buy
Color: Red
I like the cover. It is different. Vibrant color and nice grip. A tad bulky but it is a cover...good quality the few months I have had it
