No one will tell you they love the way these clip and feel for good reason. They are heavy and the gates are very prone to attracting grit that makes them clip fairly miserably. I highly recommend waiting and getting a quickdraw set after you've been able to compare several types that way you can actually try them out on the rock.

Instead, if you only have cash enough for these, take a look at the Ace or Faders brand names - they will likely outperform the OP Classic biners on these and be lighter, cheaper and smoother to boot.

I totally dig them. Shaving grams usually isn't my major concern but shaving that much bulk is a very good thing. I've been using them since they first came out and I've been very happy with them.

For opposing muscles, it's very good. For contracting grip muscles it's nearly worthless. I started using it as a carpal tunnel rehab thing. I think it's helped quite a bit at getting my opposing muscles better balanced. From my research on it though, don't plan on it making you climb harder, but plan on it making injuries less common. Mis-blananced hand muscles are blamed for a lot of the climber's hand injuries.

Overall, I like them. They aren't the smoothest action and amazing materials finish that you might get from say a BD, but at the same time, they aren't hard to place, they are damn light for the price and have a decent expansion range. Considering I picked up all 7 for $210, I consider it a bargin.

The triggers do have a tendency to ride up, but I've ran into this on other cams as well. I put a tiny dab of silicone on the tigger holes where it meets the wire and it hasn't done it since.

The smaller sizes place fine and I never found the larger ones to walk as long as they were properly extended.

The Pulsars are much more stable than the robot cams (which have been known to walk in larger placements), granted you have to have a wider placement to support the wider head as well.

I wouldn't take them over a nice set of BDs for large and aliens for small, but they certainly beat the heck out of not having any cams.

My recommendation, if you can spare the cash, go with the higher dollar cams, but if it's these or hexes, get these.

I was very suprised by it. As far as helmets it's super light weight and very comfortable. I'm glad it's rated because otherwise I wouldn't trust it as it's so light. Really nice adjustment points and good padding. Looks nice to boot.
