I have two set of Chris King Ti cages. These are simply the best I have ever used. I have used steel, plastic, and carbon. I have never lost a bottle - with the exception of "operator error" from my Ti cages. The write-up is correct - you can cold form these to your heart's content. Being unfinished metal, they clean up easy and do not accumulate scum from your drink mix. I affix them to the frame with the supplied screws and use a bit of grease on the threads. Doing this, the treads will always back off easily. Lastly, there is little or no weight penalty when you use these (if you care a but a few grams, here and there). Lastly, they look cool on the bike.
