This appears to be a good service. Why do you not put the date of each of your reviews? For example, MailChimp offers live chat but you say it does not. I am assuming that you reviewed the product before that support feature was added. These products are changing rapidly, and date of review is an important thing to know. Full disclosure of your interests, or a statement about your objectivity, would also be reassuring as well.
