I haven't had one complaint yet, haven't dropped any bottles yet, and I don't think I will, it holds them pretty tightly.
I have had one of the Profile seat post mounted racks on my road bike for years and have no complaints. I can fit a nice size bag between the cages and the seat. I tried the seat rail model on my tri bike and hated it because I couldn't figure a reasonable way to carry tubes and co2 without it looking like some modern art sculpture.
