Well for me I have found the to be a **** shoot, at least the ones under $100. I have a Moultrie and it has done well so far. I'm a video guys so my only disappointment with the Moulftie is it only has a 10 second video. I have a Stealth that has the ability to set videos from 10 to 180 seconds and has sound. The night IR is great out to about 10', which makes its worthless. Had a Primos that I like but it was sent back 3 times for fixing, I think I got a new one each time, and a some point they got tired of me and said no more. My bride just got one for her son for Christmas, a Browning, for +/- $150 so we are hoping paying more gets more. One positive about the Primos was that it had and internal battery that stored the date and time, the others I spoke of don't and it's a pain when changing batteries to rest everything.
I will say they have become really popular, everybody's getting one these days.
