Checking a home unit sd card instead of walking thru your hunting area is the main reason I spent the money initially. The system works perfectly for that, is an outstanding feature, and you'll appreciate it. Every single cam manufacturer has some sort of quality issue, Cuddeback is not perfect, but there's no quality advantage looking elsewhere. Battery use is maybe a little more than the average cam, but when it comes to systems, especially cell cam systems, it's typical. And there's solar options to help with that. No issues to worry about there.
You'll likely do what I did, due to the cost of getting started: No cell unit, and checking the home unit card. Like I said before, you'll love that feature for sure. Then you'll likely bite the bullet, cause you want more up to date info, and you'll go for the cell camera. You'll find it's worth the money to know when big boy is on his feet in your area, if that's your purpose.
The system can be a little glitchy, but I'm not sure there's a system out there that is immune to glitches. All things considered, after running this system for 3 years now, and although the price point is high (for a guy like me) I'm still enamored with this technology, and I feel the system has been a good value for my money. It's got my recommendation.
