I don't accept any money, free products, or anything else of value from the companies whose products I cover or from their public relations or advertising agencies.

The products I review are typically lent to me by their manufacturers for a few weeks or months. I return any products I am lent for review, except for items of minor value that companies typically don't want back. In the case of these items, I either discard them or give them away to charity.

Companies often visit my office, or invite me to theirs, to brief me on new products, Web sites, or software before they are released - usually a few weeks or days ahead of time. I don't review most of these products.
