Received my LightDims today - you get a lot of them! I used the 50% version on the TV. It leaves the LED still visible, but dim enough that you don't even notice it unless you look directly at it. I've been going around the house applying the little dots here and there to great effect.
The web site had a survey in which one of the questions was about a possible future "TravelDims" product which I'd be thrilled with. I can't count the number of times I've been in hotel rooms with bright and/or flashing LEDs from smoke alarms, TVs and more that I'd like to "dim" with a reusable sticker. I hope they make those. (In the meantime, I pack a roll of electrical tape!)
