got the brilliant evolution 6 pack for around 20 bucks during one of those flash sales and threw a couple in my carry on before the last dallas to chicago run. stuck one under the cabinet in the hotel bathroom and another by the door, they pick up movement so quick even with the anc headphones still on from the flight. woke up middle of the night for water and it lit the whole path without blinding me, battery still going strong after a week of testing at home and three hotels. only tiny thing is the sticky pads arent the strongest on textured walls but i just used the screws. worth it for anyone whos ever stubbed a toe in a strange room at 3am after a redeye.
