Dive-xtras sierra trigger issues

[rcn]

The reed switch does not sensor the trigger magnet when everything is assembled. When moving the magnet directly next to the switch it runs the prop. Dive-xtra suggests ordering a new rod.

How common is the fault caused by a weak magnet? Should I order a rod and take my chances? USD 65 plus shipping and handling to Sweden so I am eager to find the right corrective action.
