I tend to find them a bit boring, but fairly easy. When my PS bankroll needs a boost, I play these. I play few hands, mostly premium, and once I get a big stack, I sit on it.
When these things started, they were donkfests. No longer. It can take up to an hour to complete with a careful group of players.
I play poker more for fun than for money. (Good thing, that!) The jockeying for survival in DONs is not particularly entertaining. Not as fun as a satellite. And I don't really feel like a "winner" at the end. Someone else makes a mistake and boom, it's over. But if I only wanted to make money and that was all, these would be high on my list of games to play.
