I was a little skeptical when i first bought these... I wasn't sure what I would think of the curve design, I didn't know if I'd like the wire slings, and I thought they were a little steep in price... All that was put to rest the first time i used them... every single placement was bomb-proof, and the wire slings helped finding better placements a little deeper in cracks... You learn really fast not to place the smaller ones too deep, though, because they can be a pain to remove from thinner cracks...

Overall, I learned that these were worth every penny, as I found myself using them way more than my cams and nuts... I trust them completely, because in a good placement they feel like they could hold a whale...

I love these hexes. I have not tried any other brands, but I have no complaints whatsoever about these. I am a passive gear guy for the most part (even though I have a full range of cams), so I usually place 2 or 3 of these hexes every climb. So far I have not climbed one crack without placing a Metolius Curved Hex. Some say that wired hexes are hard to place in cammping mode, but I disagree. I find it very easy and fast. I can place these faster than I can place a cam.

I HIGHLY recomend the Metolius Curved Hexes.
