Personally I like to play it. I've had pretty good luck with it as I have won $5 once and 40 feathers another time, out of the 4 weeks I have played. And you do have the option to keep your 20 feathers plus an extra 5, if you decide to not to take the prize.
I won a referral today! I am wondering how long it takes to get that added to my account. I also won 40 feathers last week. I look forward to Mondays, that is the day I do it!
