I got this thing in the mail and was excited to go out shooting over the Thanksgiving holiday. Before putting it on the gun, I put in the battery and pointed it at the floor, nice bright red dot. My kids tried to pounce on it like Cats on Youtube, so I humored them for a few minutes and then it started to fade out. I removed the battery and put it back in and it worked for a few seconds then faded out again. I figured it was a bad battery. Broke out the volt meter and it was 2.9 Volts. That should still work. I emailed CT Customer Service and waited a few days, after not getting a response I went and bought new batteries, still no luck. I'm pretty disappointed that something this expensive failed so quickly. I haven't heard back from Crimson Trace yet, granted I emailed then on Thanksgiving, but 6 days later, still no response.
Pros: Nice smooth integration with gun
Cons: Only worked for 5 minutes.
