This is a bit fiddley setting it up with all the fasteners but once it's on it works great for me. I put it on my BH G7 to have another bottle holder for longer rides (centuries) without getting in the way of throwing my leg over the saddle. It holds the bottles that are designed for it very well, bottle launchs for me yet including a few bumpy railroad crossings. It is a bit difficult to pull a bottle out of though, need to twist it a bit to get it out. I haven't tried it with full Camelbak bottles, and probably won't as I have heard those won't stay in, empty Camelbaks stay in fine though. As soon as I finish my first bottle from a frame mount bottle holder I swap it with the one in this saddle mount so I can finish the uninsulated bottle before it get's too warm. I would definitely recommend this one for anybody looking for a single bottle holder to attach to their saddle rails.
