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."

Very handy to have to spot them easily
Color: Dark Blue
Love the cases, have a different color on each rooms tv. Hopefully it will protect from a drop as that is what prompted me to buy it. We cracked the screen on our last remote and they are expensive to replace. Good price
