google.tt is an official domain owned by Google. Of course, they're the best out there. Safe site and trusted sources for me. Be aware of the ad results. I wish there were better ways to contact the customer support/help/feedback team.
WARNING: If Google is so wonderful and trustworthy, why is it that they track virtually my entire activity on the web? I don't recall them asking my permission. If you value your privacy on the internet, stay away from Google.
Works great on couples who got home from their busy, stressful, skitzophrenic and painful workplace all sweaty and tired and they need a jump-start with their love to get into the romantic mood so they go to Google find the best stimuating websites in the world (^_^).
