so, delayed start doesn't exist but delayed end does.  It is not intuitive to find, you have to bring the alt menu then look for it each time.  also when i set it to end at 6:30am, it would start then say it'll end at 5:30am.  I am on EV rate, so really would like this be "smart" with menus to always start only after certain hours. 

also, i didn't get a "quick start guide" which is strange, bought from Costco.  the paper manual was not really helpful.  also there's what looks like a soap dish with "Samsung" printed on it, what is it?  i used it to clean the lint screen but it doesn't really work that well.  and lint screen is a pain to clean well.
