True but at the same time 5 cheap ones is better then 1 pricy one assuming all work. With several around the room you know if one goes bad or if you have hot zones. At one point I had like 3-5 in a 4x4 tent and I try to hang several In a room
Thats like saying sleeping with 7 old whores with no teeth and hairy armpits is better then fucking one hot 18 year old because it saved some bucks.
