by Nicholas Awesome Micro cams
These are my favorite of the micro cams. I have used wild countrys, metolius master cams & TCU's, aliens, X4's, trangos etc. The C3 is definetly my favorite. They fit pretty well where 4CU's don't and where 4CU's do. The shape of the lobes actually reduces pressure on the rock because of the taper. Tighter placements have more surface area contact on the rock which makes your cams less likely to rip out. I have whipped many times on these cams down to the 00 size and I have never had an issue with them. I have even whipped on them with only 2 lobes engaged and the cams held. Some people are wigged out by the flat stem shape but it really doesn't matter. The stems just bend when you fall on them and then they return to their normal shape eventually. Perhaps the best thing about these cams is they just don't get stuck. I have never used any other cams that clean out of over-camed placements like these do. They are so light and reliable, I hardly ever do a route without them.

Rated 4 out of 5 by Quin Trust 'em, they're bomber.
These are great micro's. They stay well placed even when pulled up and down by the rope as you climb above them. They can rotate up and down, but never seem to walk much. Took me a while to trust them like I do my c4's, but now I love plugging them in. My one complaint is that the smaller sizes seem a bit limited as far as placement goes; The rubber casing that protects the stem and wires gets wider as it moves away from the lobes. This prevents the unit from being able to be placed as far into a crack as I would like sometimes. Haven't had any problems with the red and yellow though. Still worth filling out your rack with though.

These things rock in small features, especially horizontals. Really nice addition to Aliens and TCU's to cover your butt on thin face and tiny cracks!

Rated 5 out of 5 by Ben Perfect for well....Everything
The C4 is the proven, hard working, and all around leader of small cams.
From desert grime to ice and rain I have never had a problem with these cams, an essential to trad climbers and alpinists alike
Black Diamond killed it with this one.

Tiny cracks, flares, these little cams seem to fit many places where no other piece will work. I find the stiffness of the C3's great for slotting into finicky placements. Irreplaceable in my opinion.

Rated 5 out of 5 by LibeckiTheTimeisNow Get them on your rack if you want the goods
Been using these all over the world. These have been with me on dozens of expeditions and first ascents.
If you do not have them on your rack, you should.
Do yourself a favor and get them.

C3s flat out rock. Best micro cams on the market. Great for granite.

Rated 5 out of 5 by Jazz Durable, awesome in flared cracks and pin scars
C3s are a great choice for thin cracks, particularly in stone where flared cracks or piton scars make it more difficult to find placements for wider, four-cam units. The lateral stiffness means I can slot the C3s more easily and also makes them easier to remove from cracks compared to laterally flexible cams. I am always amazed at the durability of even the small sizes compared to other brands of cams. Most of my original C3s from 2007 are still going strong after lots of whippers!
