I can't attest to all sizes since I only have the 00, but it is an excellent piece of gear. The only thing I would consider getting for such a small size. C3's are good, but they have a double stem which is absurd for a cam that is supposed to fit in the smallest and hardest to protect cracks. the single stem is much more versatile. It won't walk at all and it feels solid. haven't fallen on one so i can't say much about it's durability. the biggest downside i have found is that it is pretty easy to get stuck, but that is likely to happen with any very small cam.
