So I was breaking DR neons every 2 weeks or so, and I emailed DR about it, receiving no reply. A couple months later, I tried again, and I recently got a reply. They're sending me a couple replacement packs. Nice people and the 2nd attempt was quite prompt, even if the first slipped through the cracks. I'm still on the fence about QC with the strings though. I play with a very hard attack when I am on stage, but it is my opinion that bassists shouldn't be breaking strings.
