Takes a lot of practice, but it's worth it
There is definitely a learning curve to using these.  The first time I tried it, I ended up with a lot of hair that didn't make it into the clip.  In subsequent tries, I ended up with the hairs at the very top of my head sticking up or outside the clip, and finally I ended up with the clip too far up on my head which resulted in my hair looking like a literal pony's tail!  But with continued practice, this clip ends up being very comfortable to wear, looking nice overall, and my hair looks like a soft and feminine fall of hair (see photos).  I'm glad I persevered because it's my preferred way to wear my hair now.
