I use a Cobra Viper sight. The adjustments are easy to use when sighting it in. The pins are bright. It comes with an ultra-violet light you can turn on as it gets dark which really makes them bright. I don't use the light for a couple reasons:
1. It tends to come loose and creates a little vibration noise. I think if you wrap some plumber's tape around the threads of the light before you screw it in, it will take care of the problem.
2. I don't think you can enter a buck into the Pope and Young Recordbooks with any electronic device attached to your bow (if that means anything to you).
Overall, I think it's a good buy. I give this sight **** (4 out of 5 stars).
