Yes, I have one of these. I have used it out to 1000 yards so far. You can see your bullet holes, especially if you use a white and orange target. Targets with a lot of black don't work well (black holes on black target), but the orange/white targets wok great.
The wireless connectivity works well. At 1000 yards, it is perfectly clear. They say it will go 2500 yards, and I have no reason to think it won't.
The setup is small, and its quick to set up. The battery has lasted for every range session, so no problems there.
Overall, the TargetCam is very helpful.
Pyrofx, I think you are talking about the Bullseye system. The TargetCam doesn't have software or a router.
