I haven't tried them, but I like the design. It looks like they are made from one sheet of carbon fiber to form a uniform blade vs. two carbon fiber blades attached to a fragile hub. I think the ones in the post are knock offs of t-motors's brand. I want to try t-motors props, but they are extremely expensive.
You're probably right and the T-motors as well as the props are extremely expensive but as someone said, "We don't build them to crash, we build them to fly..."
I ended up buying these, because they look like a direct Graupner rip-off and they're made of carbon fiber. http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=792&productname=
I'll keep you posted once I get them and everything built as to whether or not they are quiet. I'm hoping they are because you can hear everything when you fly and it gets annoying. My old APC props were ok but they were not quiet at all. The new props are 11x5 carbon fiber Graupner rip-offs and the old ones where APC 10x5 Hobbyking APC rip-offs
Check this out, I found a YouTube video of a the RcTimer slowfly props in carbon fiber. They seem pretty strong and also very quiet. You can get an idea of that from the video.

Here's a follow-up video to that. These are the same Rctimer carbon fiber props and this guy broke one in a crash, note where the prop broke, right at the hub where the weakpoint is...this is common with slowfly props. Also take note of how strong the actual blade portion is and how much force it takes him to snap it. This is why I like the Graupner design where the hub connection is the strongest point and again I've had slowfly props self destruct in flight under heavy load.
