This solar panel is fantastic! I bought two of these about a month ago. Have multiple Tactacams and connect to them! Been using for a few months and the cameras also have backup batteries. Still fits 100%! Yes, I clean my SD cards. They have a lot of photos of pigs and deer, so I took a lot of photos. Most importantly, make sure the solar panel has access to sunlight for part of the day and is doing what it was designed to do! HIGHLY RECOMMENDED!
