I also had a similar one with a different clamp design but I couldn't tighten the cups enough to hold the saddle. It slipped at basically every road bump. I changed to one of these and have no regrets since. Except for the fact that I had to change one too long screw because it drilled into the carbon shell of my saddle
Thanks, that was the one I was originally looking at. In hindsight it is a better design, if the clamp fails to serve its purpose I'll reconsider! Had the same screw problem with my stock alloy seatpost.
