This is a great system that will pay for itself in short time especially with multiple calibers. In smaller calibers the laser doesn't seem as defined but plenty good enough to complete sighting in. Bright sunlight will also negate the effectiveness but choose early/late daylight or overcast and its great. The wire to the battery pack can make closing the chamber to lock in the aimshot hard especially with close actions like a Sako but with a fiddle around you can get it set to use - overall a great system well worth it
Pros: easy to use
Cons: hard to close bolt with wire, arbour can get stuck in tight chambers, bright sunlight will limit range
