I don't think you need to badger them. Relax, the parts will come in snail mail with no confirmation.
and about the 2 YEAR WARRANTY;
I have asked and received answer, including a clarification about S&B's warranty.
There is one 2 year time period during which they will repair or replace a defective device. It begins on the day S&B first receives a returned defective device. Sounded odd at first, so I asked for an explanation. I'll try to illustrate my understanding of the policy with an example.
Example; Buy a Crafty or Mighty on Jan. 1st, 2015. Happy camper for 5 months, say, til June 1, and it stops working (assuming not a battery wear & tear issue). It is returned in mail and received by S&B on June 6, and they examine and determine that the problem is defective and as such, covered. They send out a replacement device on June 7. In this scenario, June 6, 2015 has become the begin date of the 2 year warranty period. It will never reset, regardless of how many subsequent devices fail or are upgraded or returned or shipped out.
