Red dots star burst too much for my eyes. Im an eotech fan, some reason it works best for me. so i have to turn it on and off because of the 600 hr battery life. Lol. Guess if someone is close enough before i turn it on ill be shooting through empty glass point and shoot.
Most people only drive maybe 2 hours a day. So if you have a battery thats even rated at a year of constant on but has shake awake. On 2 hours a day would last you 12 years
