I own the Apexel lens and have used it a lot. I suspect that I initially chose it because it was the cheapest one on Amazon that looked like it would do the trick. After unknowingly dropping it during a hike I realized that, considering how cheap and tiny they are, I ought to have a spare in my pack. I found the one I dropped on my return trip, undamaged, so that was a nice surprise.
When I went to buy a replacement on Amazon the Apexel was more expensive than a similar lens branded as Xenvo, so I bought the Xenvo as my backup. When it arrived I liked the clip better, and it seems to take better pictures, so it’s now become my main clip-on macro lens, and the Apexel is the backup.
This is the Xenvo lens that I bought (it comes with a couple of other lenses that I don’t really have a use for): https://www.amazon.com/Xenvo-iPhone-Camera-Lens-Clip/dp/B01A6D2JVI/
Looking at Amazon right now, this other lens looks identical and ~40% cheaper. This low-end cheapo stuff is often copied from factory to factory in China, so It could be the same, or it could be worse or maybe even better than the Xenvo. It’s always a bit of a gamble but if I was in need of a backup now I’d probably be buying this one: https://www.amazon.com/NEEWER-Accessories-Compatible-Samsung-Smartphone/dp/B0F6C19RG7/
