I have read in this forum and others about the ZD30 Grenade problem. Now I have a 2001 (although built in OCT 2000) GU with the ZD30. It has over 300,000 K's on it. I have only had it for 3 months and average about 1000k's per month.

Should I be worried? Or has the time bomb failed to go off (so to speak).
