Anyone own one of these that actually works? Got one over a year ago and it took all black, all white or very out of focus pics. Emailed company, they were very helpful. I sent back cam and they sent a brand new one. 1st set of batteries took a few hundred pics very well, since than it uses batteries up in less than a week, flash never fires when triggered after dark unless animal hangs around camera til it takes a few pics and than it might work. Anyone elsehaving these problems?
