Some like red dots, some don't. I do on my shotgun, but prefer a traditional scope on my Muzzleloader. I'd say find a store with a nice selection and check them all out. The big store near here has a stock mockup that they can put the various scopes on so you can shoulder it and check them out. Some, like Uncle Matt above, have concerns about the battery. My holosights will flash when you turn them on if the battery is below 20%, at which point I change them. I change my red-dot battery at the beginning of the season, whether it needs it or not, though I believe it also has a blinking-if-low feature. With over 100 hrs of continuous battery life, I have never had a problem. They all have auto shutoffs, typically at about 8 hours, so you don't have to worry about them dying between hunts if you forget to turn them off. One other important point with any red-dot is to routinely check it while hunting to make sure the brightness is what you need as it gets lighter/darker out, or as you move from the field into the woods, etc. I will admit that I have shouldered my shotgun for a shot near dusk and just about missed a shot because the dot was too bright. It's something I just discipline myself to routinely check now.
