Christopher M.wrote a review of Wild Country Astro Quickdraw - 5 Pack on November 17, 2011
Wow, for such a simple device carabiners have progressed remarkably during my climbing career (~15 years). I loved my Petzl Spirits back in '97, but they were spendy ($10-$11), and compared to the Astro, relatively heavy at about 49g. Now you can get a 29g carabiner that is very smooth and well made for about $6 - sold! I carry 20+ of these carabiners in a mix of about a dozen quickdraws and extendable draws for longer trad routes and have no complaints. I use Heliums for racking gear since I prefer the snag-free feature for this use, but for clipping both gear and rope the Astros work great for me. For my sport draws I still use the larger Nitros, but I think the weight savings (approx 17%) with the Astros is worthwhile for long routes with long approaches.
