Fits a Voice Roku perfectly! Aligned and snug. Impressive.
Color: Purple Glow
So I grabbed the Purple Glow. Some of the pictures threw me off. And I realize now those partially translucent pics are to show you how it fits. ::face palm:: I was surprised at how well this fits and it makes the remote bigger so for my med-large hands it is great. I was surprised how I liked the fit.
Now at first I thought I was sent the Lilac Purple. Because mine was not glowing at all after sitting in my living room for a few hours.
I took a HIGH lumen LED light and shined it on one side and went into the closet and it glowed-ish. So irradiated the thing and then it glowed pretty well.
I have seen items like this that whatever is used to make things glow fade over time. I wish there was a manufacturer date on these. I know they can make the unit and print out a new sticker. So you just never know.
I sent it back for an exchange. I do want it to glow. So we will see.
However, if it does not glow I will keep it. Since it is the best fitting and easy to take remote out to change battery.
I have had floppy covers (so useless) and super snug ones that fit perfectly but for me were a pain to on and peel off.

Well made purple remote case!
Color: Purple Glow
I was a little hesitant to get this remote cover because I wasn't sure if the controls would work well over our Roku remote, but it did not disappoint. The full face is open, giving you access to all the front controls. I was also concerned about the volume and mute button on the side, but those work well also. I got it mostly because I was constantly dropping the 'bare remote' and didn't want to have to replace that. The silicone keeps it mostly on whatever I place it on, but if it does drop, it stays nice and snug in the case with no issues. And I love that it's purple!!!

Saves my arthritic thumbs.
Color: Green Glow in the Dark
This remote case is perfect. I can place the Roku remote in the case on the table so I don't have to hold it in my hand to make changes. This is saving my arthritic thumbs.

Very good design!
Color: Green Glow in the Dark
It isn't really glow in the dark. But otherwise I am impressed. It is designed so that the remote is suspended within the silicone, rather than the silicone being a second skin for the remote. The size and the bright color do make it easier to find, especially since it gives enough bulk to the remote so that it doesn't slide so easily into the dark recesses of our sofa. To my mind, this cover ensures my remote is safer from falls. We were managing to drop it a lot. The remote by itself is remarkably slippery, I was grateful for the fast 2 day delivery.
