If I believed all the bad reviews on this I would not have one. I have added this camera to my Arlo Pro 2 that I have had in place for more than a year. I did not have any problem with connecting this add on camera and it works as expected. I have not had any issues with short battery life in my cameras(they last months) but if I am going to be walking around where the cameras are all day I turn them off and put them back on when finished.The free storage supplied is a real plus.Downside :I will say that there is about a 20 second delay from "actual" to notification to I pad/I phone. Very happy.
