Thanks so much guys. I installed them last night - trying to get temp adjusted "perfectly" now. Seem like nice heaters - just wonder why they felt the need for such...substantial... cords. I don't think I have anything that runs INside the house that has these thick, fat cords! But anyhow - I've got one on a slight angle, and one totally horizontal - and the worrisome Stealths out and on their way back to Marineland so I can get my refund. Thank you guys!
