We purchased two microscope cameras on December 7th and they did not arrive until yesterday, January 5th. Like many others have said, I had no idea that my purchase was coming from China. The fact that the site was not forthcoming with that information definitely feels misleading. We had trouble getting the product to work. After some research and downloading the correct application, we finally did. I'm so relieved. For those of you still having trouble with the microscope camera: I have a Samsung Note 8 phone and it came with a USB to USB-C adapter. The app CameraFi2 from the Google Store worked for me. I'm not sure what will work for the iPhone but as I bought one for my little brother and he has one, I guess I better figure it out.
