They are great, lol. I have the c-1540T (which is the traveler one). Imho it's as good as the Gitzo equivalent--only even lighter. Also have the c-3540T, which imho is also as good as the Gitzo 3-series equiv--not "as good for the price"--but AS GOOD as the Gitzo products. I like it better than any Benro/Induro/Fancier/Feisol/whatever stuff I've ever seen. From what I can tell, it's basically like buying a twin of the Gitzo stuff with a slightly different color, lol. Haven't tried the C-25xx series stuff (that looks like more of a manfrotto type one, with the flip locks instead of twist.)
I bought an e-bay carbon fiber tripod once, it was awful (Fancier or Feisol brand I forget)...it was just awful, the metal was easily chipped, the center column had play to it, all that. I ended up taking it apart and using the legs for walking sticks. I was brave and tried e-bay again and found the Horus stuff. Glad I did. The downside might be trying to get support if something ever broke.
Honestly though, i've strung a 40-some odd pound jug of water off of my c-1540T and it took it with no problems. I think the C-3540 would probably hold 100lb if you asked it too, lol. Maybe I should post a review....
From what I've seen, no one has yet became the U.S. distributor for these. Someone with some $ should jump on that.
