I noticed in the test that the retractable wide-angle lens mount is missing, in the other case not. Everything you need for this camera is all in one. You actually tie it all together when you use a wide angle. In addition, the initial installation of something sticky will take time for the product to stick firmly. So I recommend sticking the adapter first without the lens so you can stick the connection (like command strips) and then after a while you can proceed to install the lens which should stay good enough. Remember to attach the adapter in the middle. I have held my camera by the grip or tripod knowing the weight of the lens and it still holds up. I'm not as careful as I should be and mine stayed pretty decent. Wide angle and macro also work excellently. If it's still confusing, it's Camera > Lens Adapter > Macro Lens > Wide Angle Lens > Lens Cap. If you want macro, just unscrew the wide angle. Hope that helps. A great find to help a great camera.
