Something strange about this thread! I saw an email informing me of your reply, but I can't see it in the main forum thread.
Anyway, from the email - sorry to hear about the mishap, I guess that can happen with anything. I'm sure they'll swap it out for you, it's just the inconvenience.
I had issues with a brand new GMC mitre saw which had a badly adjusted laser. In the end I managed to adjust the two lasers together after an hour or so - pig of a job! It was the lesser of the evils. The supplier would have exchanged it, but the time wasted and the re-packing were not worth the hassle.
