I've heard some very negative tings about the 'Free Zen' (Inverted commas deliberate!) surveys... they're well known for not awarding the Zen, failing to load just on the final page (After they've had all your information etc).

Also, Cryptic/PWE take the stance that if the Survey has NOT awarded you the Zen, then it's Peanut Lab's fault (The people who administer the Survey), and you have to take the issue up with them directly.

One to avoid in my opinion
