The cameras themselves are fine and inexpensive. However this company is conducting some major false advertising. I contacted them directly before buying asking if an Android tablet would work. They assured me that there cameras work on Android tablets. Not true at all with the brand new Samsung Galaxy tablet I purchased. Then I contacted them again and was told the cameras only work on phones. So if you're looking to use the camera as a baby monitor that's definitely not realistic to have it on your phone all the time. If they had come out and said this when I initially asked then I wouldn't be so angry. But having an app that only works on phones in 2022 is laughable. Also, forget about using them with any Amazon tablet.
