I haven't used the Camp, but my measured weight for a Superfly is just 29grams too (as stated by a user for the Nano weight). They are light and very useful. A real carabiner at just about one ounce.
Kevin asked for more information. I weighed five of them to get a better weight (they are officially listed as 30grams). The group of five weighed 144 grams (I'm using a Ohaus triple beam balance which is accurate to far less than a gram). That weight is under 29 grams per carabiner. The minor axis strength is less than a Camp Nano (7 verus 10kN) but the major axis is somewhat more (24 versus 22kN).
