The dyneema dogbones are well made (same or better than the BD ones I own) and the biners have a nice feel to them. There's lighter weight biners and ones without the hooked nose, but I was able to get these ones at a good deal and I'm happy with them. Using mostly as lightly draws for trad/alpine climbing. My only beef is that the open gate strength of the Nano 22 is higher, despite these biners being heavier!
