As a key hanger, this is just as functional as the titanium version but is even lighter, which is a win for keeping my keys as light as possible. Another bonus is that the carbon fiber seems to grip my belt loop just a little tighter than the titanium version, which makes it feel even more secure. I cannot comment on the bottle-opening capabilities, but my guess is the titanium version is better in that capacity. Overall, I am satisfied with this simple device.

The clip did not open enough for my thick belt. I was afraid it would break if I tried to force in on. It should work fine on a thin belt.

I've been using this almost daily for a couple weeks now. My main use case is keeping my keys in place when jogging and to prevent them from slipping out of my pocket when driving. (It's never fun to realize your wireless car key fell underneath the seat when you're 2 miles into a hike).

Pros:
- So lightweight it feels like almost nothing
- Looks pretty cool but subtle (I like the matte CF)
- The edge around the hole for attaching to a ring is nice and thin making it fairly easy to attach to various rings and the opening size is just right.
- Mostly does what it's meant to do

Cons:
- There is very little tension due to being made of solid carbon fiber. If you're attaching to something fairly slim it's not unlikely that it could slip off. If there was less of a gap, this would be a lot more useful to have stronger tension.
- As another reviewer mentioned, the edges are pretty sharp. I've mostly gotten used to it but might eventually try sanding them down a bit.

If there was a titanium version or another similar item with more tension this would be perfect and I'd pick up another in a heartbeat.

Great for your keys. Looking for something simple yet effective and stylish? This is it!

Well built! Top notch! Thank you!
