Have u ever won these giveaways?(18+only)

Hey,
One of my friends recommended me these websites to try out and win some cool, free stuff.
Have you ever won anything from them?
You can join for free with your email, so I think it's worth a shot, but I'm not sure if they work.
gift cards, or electronics.....so much stuff.
