Add me to the list of people who do not trust Dustin Abbot and that is my definitive review.

Reviewers make money through affiliate link purchases. Positive reviews benefit them. That doesn’t necessarily mean they’re dishonest, but it does mean they’re not unbiased.

Sorry. It means they might be unbiased. They may also be completely unbiased.

I have idea if Abbot is biased or not, but I consider his reviews to be just about the most reliable on the internet. Seems quite willing to tell all about the negatives and is generally rational and fairly even keeled when discussing the positives. Shows a lot of examples and test results. Avoids the hyperbole that is the norm on the internet, so I can't think of anyone better off-hand.
