I think they are fairly hard. I've been doing them for ages and they rarely take me longer than 15 minutes, and usually under 10. But for someone new to them they are definitely hard enough.
As we've seen with normal Sudokus, they have found it necessary to give an easier one and a harder one each day, as they cater to newer and more experienced audiences that way.
I think they would have trouble finding a lot more space for two Killers a day, so they have to find a medium.
It would be good if they found some very hard Killers (having worked out how to rate them properly) and published them on a particular day.
I'm hooked on these Slitherlinks now, and have found a decent site from which to get them.
