Love the glow
Color: Glow Green + Glow Blue
All I can say is I walk into a dark room and don’t have to look for my remote. The glow works perfect.

Little snug
Color: Glow Green + Glow Blue
Item is as described. I had two issues. I am a male with big hands and strap will not fit. Other issue is the bottom is too snug fitting to allow charger to connect properly. Otherwise, all is good.

Nice sleeve for the remote
Color: Black not Glow + Navy not Glow, Color: Black not Glow + Navy not Glow
These fit well on my remote. Have a cut out for the charging port so no need to remove the case for charging. These give a little more girth to the remote thus making it easier to hold without it slipping out of my hand so easily.
