My new T3 works pretty good. I am used to my 640 resolution AGM so it took some getting used to. It came with two Rix branded 18650 batteries, but they were different. One flat top and one button top. I was told by Rix when I contacted them, that both would work. The flat top battery is very difficult to fit into the unit and close the compartment. I was disappointed when told it would work, but if I wanted, I could ship the one battery back and they would send me a button top replacement. I don't have time or patience to package one battery, drive to town, pay shipping, and wait / hope for another battery... I feel like they didn't believe me that it didn't fit... I'm 70 and old-fashioned I guess... It just doesn't sit well to be brushed off somehow...
