I am an avid hunter and outdoorsman and also a developer/creator/user of outdoor products. This purchase is my first exposure to CB Cams. Even though they've only been in the field for 3 weeks, I am impressed. I had to call tech support for a question on the initial setup but that didn't take very long to resolve and T/S was very knowledgeable and friendly. The online configuration of the cams is a HUGE plus for me along with a daily email on pics taken and status of the cams (1 Home and 1 field cam currently). The day and night pics are clear and resolution is good. This is my first exposure to any cam that uses D batteries. I read one review before I purchased that indicated the cams drained the D batteries quickly but so far, I've not seen that. But just in case, I bought the extra battery pack that holds 6 D's, it was an easy strap onto the tree near the cam and the plug in was very easy as well. Learning how to navigate the menu on the cam took a little more time than usual but became easy after the first few times of usage. I have used MANY cam flavors in the past and always had many negatives with them, but so far with CB, I'm not seeing negatives. Time will tell if that changes. I do recommend these cam's.
