I've had one of these for about 8 months or so. I'm very fond of it but like all equipment, be mindful of how you use it.

Pros:
- Dedicated piece of hardware (clear purpose, won't get used for something else, known history)
- Easy to select a good distance from the anchor point due to the variable length / multiple loops.
- It clips onto your harness pretty tidily
- Fast to adjust if you want to take in some slack by clipping a closer loop with another biner. You don't need to undo the original clip in point to do this either so that's nice and safe.
- ***Major plus that I haven't seen noted above: If you clip in to the power point with a mid-length loop it's possible to clip two loops at the anchor and then clip the tail back to your belay loop for a redundant pair of loops connecting you to the anchor. This will also work nicely for an extended rappel point so you have some redundancy there as well.

Cons:
- Dedicated piece of hardware. (not useful for anything else)
- Expensive compared to using a couple slings.
- Even with the tidy clip in length, other gear may get snagged on it occasionally.
- Attachment point Doesn't rotate to spread wear and tear: With so many loops there are a lot of areas to inspect to make sure it's not wearing out somewhere. One thing that people may not consider here is that if you are using a single loop, if any of these loops fail you are toast if you aren't using a rope tie-in too (I do this). On the same note, having a dedicated end for girth-hitching to your harness means the same point of contact between this and your harness and the same point of wear and stress for the material. Bottom line: Inspect your gear.

This little bit of webbing is great, just a few dollars more than a daisy, but with way more safety. I can clip into the anchors, set up my rap on one of the loops, metolius shows pictures of usings the PAS instead of a sling..for whatever reason...the only complaint I have with this thing is that sometimes it feels just a little on the short side.

The PAS was great for keeping the belay stations organized. Yosemite with three people on multi pitch climbs just proved this all the more.
I can't imagine the pain of using my slings now, and won't have to.

I used to use a runner for this, well this thing blows it away, lets, me clip the master point easily and pick how far from the point I want to stand/hang which is so incredibly handy to belay the second.

I used mine for the first time in Potrero. I will definitely make regular use of it on trad as well. While it lacks some of the versatility of traditional slings, it is full strength at every loop and therefore more useful than a daisy. It is bulkier than a daisy, but I didn't find this to be a problem. Hard to beat for a single piece that will handle all of your personal anchoring needs.
