Received my Urvoi braided sport loop today. Though I don't have an OEM to compare it against, it does indeed have the metal ends and flared out band where it attaches to the ends, just like the OEM. Quality seems great, and I'm almost completely happy with it.
I say almost, because I'm just a little on the fence about the size. My wrist is in the ballpark of 165mm, which for a 44mm watch is right on the border of the small and medium sizes. I don't like to wear my watch loose/floppy, so I opted for the small, and I'd say it's just slightly on the "too snug" side. Definitely not intolerable, and perhaps it will loosen up after being worn a while, but this demonstrates the issue with third-party loop bands, since although Apple offers numerous sizes with small increments, these are only available in S-M-L, so for someone like me (at the upper end of S and lower end of M), the band is either going to be slightly too tight or slightly too loose.
That being said, I still think this is the best size for me, as I'd prefer it to be a little snug rather than a little loose.
Edit: I should add, after several days of wear, though the band is slightly on the tight side, I've experienced zero discomfort from it – I barely feel I'm wearing the watch.
