ok, so i just got my dx laser and after about 30 secs of use, a faint line fades into the spot, it looks like O its not a big prob, im just wondering y it does this after i leave it off for a couple of mins, the line goes away
My dx true 30 has been surprisingly durable. Because it was so cheap I'm careless with it and I have put it through all kinds of abuse and it still works great. I have carried it around in a backpack where it constantly collided with heavy books and it has survived being bashed/frozen/scratched/and mistreated in general.
