If I build an unsafe boiler, and gift it to you, and then it explodes and kills you - am I not liable because it was a gift and not a sale? Can I disclaim away any liability and "fitness for purpose" when I gift you the boiler?
ETA: the first couple of Google results say that no, product liability can't be disclaimed away - particularly when there is no contract or opportunity for bargaining. I am very much not a lawyer but this sounds correct to me (i.e. this is what the law is).
