I've been a valid class member of a half-dozen class action settlements in the past few years; Western Digital, Belkin, VistaPrint, Epson, and a few others I can't remember. The Belkin settlement was potentially the best compensation; up to two full refunds with proof of purchase or 50% off the purchase price of up to three Belkin products without proof of purchase.
I've never filed the forms for a single one of them, because I strongly disagreed with the basis of these frivolous actions. Most were brought by ignorant consumers who were "mislead" only due to their own ignorance, or just opportunistic lawsuits by consumers who knew better but wanted to exploit the system by seizing upon the slightest deviation from advertised specs.
e.g. Belkin was sued because the actual 'real world' speeds of various networking products were less than the advertised maximum. Duh! What informed consumer does not know that maximum published speeds of any bus or interface are only theoretical or attainable in the most optimal conditions rarely found in the real world?
We could sue every computer company, component manufacturer, and chipset vendor for 'false' and 'misleading' advertising because we never got 133MB/sec from the PCI Bus. Same goes for UDMA-33/66/100/133, USB1.1, USB2.0, SATA 1.5Mbps, SATA 3Mbps, dial-up and broadband internet access, and numerous other busses or interfaces.
Companies cannot rationally be expected to advertise products so that every conceivable caveat, exception, or risk will be known to the lowest common denominator among consumers. Otherwise, every single consumer product on the market would have a requirement that the consumer complete a three-day seminar before the product can be placed into use.
I can see the activation schemes now..."please provide your certification code that you received upon successful completion of the required three-day consumer education course for your Sharpie pen. This completion code will allow you to unlock the $300 tamper-resistant device encasing your $2.00 product, which has a final retail price of $2000 due to the costs of producing and conducting comprehensive consumer education courses for each of our consumer products."
