Lux Phone Camera Kits

Is the macro lens supposed to be loose and just fall out of the ring? There is a round plastic ring that, I assume, is supposed to hold the lens in place. Mine just falls out and now the ring is cracked because I tried to push it back in place to hold the lens in.

You are correct, there is 5 lenses! Thank you for clarification. I've also tested just the Macro lens, the results were similar to the other included lenses, as if shooting through greasy/dirty lens.

It does come with 5 lenses. The Macro and Wide are stacked together in the packaging. The Macro requires the Wide to be stacked on it to function as a Macro. The Wide must be independent to function as a Wide. Separating the two can be difficult. I find it easiest to screw the stack together into the clip, then unscrew the Wide from the Macro.
