    It's like a flexible soft plastic. It's pretty much like any low-cost TPU case. I don't know what the "carbon fiber" part means.

    Do you have a link to buy that case?

    I don't have a link to the one I bought in 2018. If you search Ebay for "Moto E4 clear TPU case", then sort by Price+Shipping, you'll find one LIKE THIS .

    Carbon fiber is used as a light weight strengthening material embedded in the soft plastic. It is very rigid, so is likely used in short strands to maintain some flexibility and shock absorbing ability.

    The kind I'd like to find I had years ago on an LG Dare. It was actually just like one piece vacuformed rubber that stretched around the case sides and back. It didn't have cut outs for the buttons. Just kind of bumps sticking further out at those locations so if you pressed there it would activate the button. Only cut outs for the camera and headphone jack.

    And they don't always specify.
    Got one here that just said E4, but it the EU version.

    Has rear opening for speaker on EU version and the headphone jack opening is wrong. (Also different noise cancelling mic location)

    The kids have broken several screen protectors with impacts. While I can't prove the screen would have cracked w/o them I know how many cracks they got with phones before using the protectors. And none with a protector on.
    (It is important to replace a cracked protector though. The boy did crack a screen with a severely cracked protector. He was lazy and didn't replace it. He go to buy a new screen instead)
    I've never used tempered glass, and now don't even use plastic film types currently. But then I don't use devices that cost more than $70 or so.
    As mentioned I paid $30 for it but it usually sells for over $100.

    Worth $6 to bot have to change devices even if I could find a similar deal easily (unlikely)

    I think the one about spreading the impact covers it.

    Most drops aren't onto smooth surfaces. So you get high pressure impact points. The glass protector spreads that out. The point force may crack the protector but it spreads it out on the actual screen.

    Try it yourself. Put a 2x4 on your chest and have someone hit it. Then move the board and take the same strike. Then try with a wider board (2x6, 2x8, piece of plywood). The larger area spreads the impact more.

    Urrrg. No need to try that. Currently recovering from a sports injury where the impact was not spread out enough!

    Sometimes (often?) with a typical TPU case they'll have a finish option that looks like carbon fiber, but is actually just a finish look. Like matte as opposed to glossy.
