In general their policy very good, but it's not quite no questions asked—they're pretty strict about the 2 hour playtime limit, which is quite a short time to decide if a game will actually be fun. In many types of games by the time you get through the tutorial and have access to all the game mechanics you're already past the two hour mark, and they also can't tell the difference between actual play time and time in the menu while you're doing something else.
EDIT: To be clear, I'm not saying it's a bad policy, there are obviously reasons for this. But it's not truly no questions asked.
