I have been using Mail Link for over two years now, and I am please to say that I am very happy with their service. Whenever I have made a phone call or sent an email I have always received a quick response. My customers are not always kind enough to include my box number when mailing, but this doesn't seem to be an issue for mail link as all my mail makes it to my box anyway. And after seeing that picture of the lab, I can rest assure my mail is being well guarded.
