I'd disagree with the above discription. I switched my entire rack over to neutrinos and have absolutley no qualms with them. They are a little smaller than other biners, but I haven't found that to be a detriment at all. They are also within 3 grams of the "super-ultralight" offerings that have since been introduced to the market.

I'm not sure I'd pay full price for them (since there are other light biners for less $), but I didn't so I have no complaints at all.
