Horton has said to send mine back for exchange. I'm leary given my limited experience with mine, the other at the store and what I have read about very, very similar situations. But I have no choice. It is not a good introduction to this brand. I now get to set my expensive new toy aside and wait a couple weeks for them to get mine and send me a new one. They did not offer to send me one out first to minimize my downtime or cover postage for their defective product.
I've had good results w/ horton warranty dept on two occasions. Think they claim 48 hr max turn around time. I shot that 3 dot and thought it was junk, imho. The 20 yd dot was huge and could not get the brightness to jibe w/ white bag target at 30 yds. Good Luck!!
