What is aramid fiber? I don't know, please go look it up and be mindful of marketing.

Synthetic materials like carbon fiber, fiberglass, composite, aramid, kevlar, etc are just fun names for the same concept. You take strands of something really strong in one aspect but catastrophically fails if twisted or sheared or rubbed against itself. That's why you lay out all the fibers in certain directions then glue them in place and hope the glue prevents situations where the fibers are weak.

When you see aramid, think amine-based (nitrogen). Carbon alone (like in carbon fiber) blocks radio frequencies so no-go for phones. Nitrogen helps the fiber form similarly strong chains without RF obstruction that pure carbon sheet linkages cause. From what I've read, aramid is closer to kevlar but doesn't require the same tension for strength. Being 0.7mm thick, it's definitely not protective and you should only think of this as an alternative skin. From what I've read, the shock absorption is somewhere between glass and plastic. You are def getting worse drop protection than any real case.

Ordered 2/7, received 2/26 (19 days, if math hard). I didn't take a picture of the box, but think fauxfiber-wrapped cardboard with foam inside. Sturdier than your Amazon package, closer to particle board tbh.

I paid $26 on aliexpress and would not recommend it if you need a case. I like the slim case but need a lip. I don't lay my display face down but still ... I love the rear, the button cutout is tolerable, and the lack of lip is a dealbreaker. I don't see any suitable alternatives so it's my daily for now.

Texture: the plastic feels amazing. Soft and grippy enough. My XPS 13 9360 has 1/10th the texture and is grippier. I have no complaints about the texture or grip and would not adjust either. It can be slippery for those concerned about that. After a week, it still looks and feels new. I'm not sure how scratch-resistamt this material is, but it definitely still feels superlative.

Finish: Minor variation/bumps at the corners. In general, straight lines are cut perfectly while rounded edges have small imperfections (<0.5mm). If you're struggling to see it in the photos, trust your eyes. I chose the camera cover variant for piece of mind (also comes in no-top/-bottom or camera-cut-out or both). You can see that small space, which I really don't like. I can feel the case creak a bit in that area, and am certain that harder-than-glass particles will accumulate and scratch the lens.

Installation: it's not terribly hard to install, but removal can be scary. The small bridge of plastic over my 3.5mm port shows some visual strain. It's not quite a crack, but the aramid plastic is clearly discolored in a fracture pattern. It only appeared when I began to very gently remove it (to take inside pics for you...).

Ergonomics: I don't like the exposed buttons but feel like cutouts would have caused problems. Hard to install/remove, prone to stress fracture were avoided by just cutting that section out. This is why we see so many cheap hard cases just omit the top and bottom. You lose a little protection and also lose a little headache.

Personally: I didn't just buy a case to protect my phone. I was rocking the very protective and great-feeling case temporarily while the aramid fiber was en route. It's big and bulky, but it feels amazing in the hand and I highly recommend it if you can grab it for under $10. This aramid fiber one is basically a skin, and I like the look and feel despite the lack of protection. I'm going to keep using it while I seek an alternative or addition for some screen protection. I don't hate screen protectors, but would prefer just an ultra-minimal 3d-printed bumper or something. This is a lot of concession and effort for a case I paid $26 for. I don't think a skin would be a suitable alternative, but for anyone interested I implore you to reconsider a slim plastic that that has top/bottom coverage. How do I truly feel: god damn does this case feel good. Forget a skin, the in-hand feel during use is amazing and I recognize that my phone is basically caseless. I'll put the rugged case over this one rather than risk breaking it from frequent removal.

Things I would change: LIP, smaller button cutout . I paid $5 for a small sheet of fake carbon fiber for wrapping cars and plan on using it to pad the gap in the camera hump. It may be too thick, or just right. I might just cut a tiny ring to "seal" the camera holes. I originally intended on surrounding the buttons so it would be more flush, but think the effort is not worth the payoff.

Other: I had the Totallee leather case for the last couple months on my 3 XL (was $8 new on amazon) and the cutouts were atrocious. After several hours with an exacto knife and a small flame, I made the buttons easier to use and the USB-C port accept my big, thick plugs. I think with those mods, that was my ideal case. Very slim but stiff, ~0.3mm lip (1mm would have been nice), and the leather rear feels fantastic while the edges are more durable plastic for daily use.
