I'd hate for this to sound like overkill, but Abine really has changed the way I use the internet for the better. I haven't had a chance to explore all of the features yet, so I can't speak on the product as a whole, but I like what I've seen so far. The opt out functions and protection against tracking are more effective and easier to use than the add-ons I was using before I found Abine.
I also like being able to see all of the accounts I've signed up for (and allowed password save permission) but forgot existed. One such site had my credit card info stored on it as well. I was able to find this easily and delete the stored access info with the Abine privacy suite.
Finally, the email alias function and identity manager allows me to send inquiries and sign up for offers and accounts without having to worry about an onslaught of followups, surveys, and spam to my main email account.
I have to give a 4 out of 4. It's just too cool and too easy to use. I would definitely recommend it to all of my fellow privacy-conscious web surfers out there.
