DOUBLE-CHECK THAT PLASTIC WRAP IS NOT DAMAGED AND THE STAPLES ARE INTACT ON THE TOP OF THE BOX!

If the box has been opened already, people don't always remember to re-insert the trigger dampers. You get the sucker home, sit it next to a neutron reflector, and property values spontaneously drop over an average 23.8km radius for the next 6-12 years (actual values dependent on local terrain and annual rainfalls).

It's on the side of the box, but nobody reads it. 🙄
