Like everyone else I got it loved it then it dimmed. Replaced batteries no go ( or I should say no glow) I gave them to everyone I knew for Christmas stocking gifts but I have 3 here that don't work. (Well 1 does in red but it so dim it does nothing). I don't know how to reach the company but it doesn't sound like it will be a successful outcome anyway. I also tried the other brand; same outcome. My first one lasted about 6 months the other 2 not even 6 weeks. But it was great for a cruise and our cabin steward was stumped as to what it was and could not believe it when I had him try it! I left it for him :) poor gu is probably trying to figure out what happened. Neat idea though
