AdGuard lied to me, so they deserve the lowest rating available. Their web site says they offer a two week trial, after three days the trial stopped and offered, "Get another 11 days free by creating an AdGuard account!" When I entered my email address, they indicated the offer was no good because my email address was already registered. If they had given me the two week trial as they promised, perhaps I might have written a more positive review. Based upon my experience, AdGuard does not keep their word to potential customers, and that makes their company not worth doing business with.
