After my grandson keep bee lining for the remote, dropped it, which made a teeny chip in it-I decided to try a cover! This is really nice. It fits great. It has a nice grippy feel to it and now it's protected. We bought the lime green one, so now we can find it a lot easier as well as having it looking pretty sleek. It a great cover.

Much better fitting

Color: White

Had to buy 2 of these cases because the first one was so well done. I bought another brand and it was such a loose fit. These are awesome!

As advertised

Color: Green Orange

Did exactly what they needed. Made the remote slightly larger so it is easier to use and less slippery.

Pretty good...

Color: Red

Red color is kind of an orange-red. Hm... Came with some kind of dust on it. Once cleaned off it's not as slippery, yet still slips on just fine. Protects the remote - and your hands from the remote's hard edges. The raised bumps on the back make it easier to pickup - without digging your fingernails into cushions or carpets as you "scoop."
