I had to use a Vortex warranty on my Venom reflex sight. I slipped and fell in a creek. Had my shotgun on my back and the gun and Venom broke my fall. Busted the sight all up. Surprisingly, it still worked, but no way I'd risk using it. Contacted Vortex and they sent me a brand new one within 2 weeks. I wouldn't have even been mad if they hadn't, since it was 100% my fault. As far as quality of the Venom, been using one the past 4 years on my turkey shotgun. One of my spring seasons is equivalent to several seasons for the average turkey hunter. Venom has performed flawlessly, love it.
Burris. Before my Vortex Venom, I used Burris Fastfire 3s. First Fastfire lasted ~2 turkey seasons before it started having electronic failures. Sent it in to Burris and they had me another in a month or so. Unfortunately, my replacement Fast Fire 3 also lasted about 2 turkey seasons until it began to experience the same type of electronic failure as the first! Burris once again replaced it. I then sold the replacement and bought a Vortex Venom.
