First of all, I'm not trying to put a damper on things. More so, trying to help with a bit of reality re the concerns. Pathetic as it is, this is life today, isn't it?
Being that your group is already having 2nd thoughts... then perhaps they should not even sell them.
It's all about liability and as a group, HUGE concerns should the worse case scenario ever happen, with attached warnings or not. And that liability could stretch out and affect each and everyone of you.
