Salaam - Hijab Crown Thoughts!

Assalamu alaikum everyone <3 I usually wear my scarf more like a dupatta/shawl than a fully wrapped hijab. For quick errands, last-minute plans, travel, or just any time I don't really bother getting all glammed up, I don't always pin or secure my scarf. Because of that it can end up looking messy - lopsided, my fringe peeking out on one side - kind of disheveled. (Quick note: I mostly wear jersey or modal materials.) I've been seeing ads and reviews for the Taj hijab crown and wanted to hear honest opinions from sisters who've tried it. 1. Is it comfortable overall? Specifically, does it bother behind the ears - I sometimes wear glasses so that area can be sensitive. 2. Which is better: the nylon version or the rubber one? I’ve heard the rubber works well for thinner hair, but my hair is very straight and quite thick, so not sure which to pick. 3. Mini or regular size? I’m petite so the mini seems tempting (and cheaper), but if the regular fits much better maybe it’s worth the extra cost. 4. Does anyone have a 3D printed pattern for it? I have a 3D printer and could try making one myself if someone can share a file. JazakAllahu khairan for any honest thoughts - I appreciate real feedback from sisters who’ve used it!
