In reply to ben_elphick:
They're great - nice and light too compared to many other cams. I had a full set and climbed very happily on them for a years until I got Dragons and Camalots for a review. I tend to use them now as they are newer, but my old 4CUs are still great when I do use them.
If you've found a good deal on them, I'd go for them without a second thought. They're great.
