A buddy of mine has them and they aren't all that bright. You can get the extra light attachment to make the pins brighter, but I didn't think the pins were all tht bright. I have the new copper john dead nutz 2 and they are really, really nice. I love them and they have all kinds of adjustments on them and the pins are very bright...even in low light conditions. The sight also has 3rd axis adjustments and is a great sight for the price. But, as far as the G5 sights go...I wouldn't buy them based on my couple of uses with them.
