This is a fantastic device that adds wifi capability to your workflow in a very successful manner. I use it for real estate photography and it is very valuable to show brokers larger size images to help them evaluate the shots. The software interface works in a manner that is very familiar to a photographer. I purchase my Cam2 in 2020 and it has served me extremely well to this day. I am ready to replace it as it seems to operate slower now, and bettery cover broke off. I wish I could buy a CamRanger3 that had faster boot up and wifi, enhanced software with a true “session” that can be recalled if you lose it, and a capture and compare feature that would allow you to have a sample image up that the new captures will compare too (like CaptureOne). Unfortunately Cam3 does not exist. I looked at, and even purchased competing products (Camfi and Case Air), but they were not nearly as effective. Non-replaceable battery is dealbreaker for Case Air. Camfi not compatable with Canon. Looks like its Cam2 for now.
