I mean I will say what I have won (and I've won twice) isn't particularly what I was hoping for, but I still feel very fortunate to have won at all and I adore the items I received. But aside from winning, I've enjoyed the experience of conversing, and having fun with new people. This event brings together everyone in one room for 2 hrs (if you stick around), and you can either sit in it silently and sulk about having to wait 2 hrs for the opportunity to win a prize, or you can goof off and enjoy the experience of meeting new people and possibly making new friends while you wait.
The experience is all about what you make of it. If you turn it in to something positive, you'll still semi-feel like a winner even if you don't win, but if you sulk and make it something negative, you'll find the entire month will sour rather quickly.
It's all up to you
