From what I am reading, it sounds like the Cuddeback E2 is one of the better models out there right now, and they have a lifetime warranty?
Are the blackout models still the big thing? Does that make that much of a difference in not spooking deer vs. a regular IR flash. Especially if the camera is in their face at a scrape? I have been using regular IR cameras where deer are just walking through and Blackout models over scrapes.
I have been running the WildGame 8MP cameras for the last two years. I have missed some pictures of deer and the flash is less than the 50ft, to really see in great detail. But most of them have been on scrapes and right off trails. For the $80 or so price I am not going to complain. Plus if I put them on public I will not be as pissed if they come up missing compared to a $100+ camera.
