I've paid for this subscription every year for decades, because I know what thorough testing they put products through, how good they are about providing warnings about products (which nobody else provides so quickly and reliably), and how intelligently they decide which standards to measure things by (safety, price, reliability, etc.) They have been a watchdog for consumers long before sites like this came along (I welcome Trustpilot also but I wonder if they don't let some cranks' comments slip through).
