I agree the letter is very carefully nuanced in lawyerweasalese.
He does not draw attention to customer rights, obligations or liabilities, only his client-Akins Group.
Best regards,
They are issuing a recall. That's what the letter is: you don't have to send the whole thing back, just send the spring to the BATFE.
Somehow I don't think there's any money left to refund. They just started selling the things, and probably already spent it all paying manufacturing & legal bills. It's not like small companies just pile up all the incoming money in a vault. Caveat emptor.
