Years ago when I first got mine, we went to KC for a baseball tournament & I thought, why bring it, it’s only a couple nights. I about fell asleep driving home a dozen or more times. I won’t go overnight now without it.
Two months ago, I threw part of my headset away thinking I had new one to replace it. That night I realized I didn’t and the garbage men had come earlier that day so the old one was gone. The next day I was miserable so I drove to my supplier 20 miles away vs. waiting the 2-3 days to get the replacement part in the mail.
I always keep the old one around as a spare...
I also scavange parts off the old one
