I heard that they dont stay in if you let them collapse, and they rattle when empty.
A bit more rattle - yes. A very, very mild annoyance at most. I frankly don't care because I know it's the bottle and not the bike (with the latter, it'd drive me up the wall until I find it and kill it). That said, I think I might take a step and fix it with some deliberately placed neoprene in the cages.
Never had an issue with collapse or the bottles staying in place, and the roads hereabouts (London and surrounding areas) are far from smooth.
Total weight with standard plastic cages is lighter or the same as most other bottle-cage combos. E.g., camelback podium is 90g for 610ml, plus at least 10g for a cage vs Elite Chrono CX total weight of around 100g. There is also a more expensive CF cage version which saves 8-10g. And aero benefits are pretty obvious just eyeballing the bottle shape and that it's now narrower than my downtube.
Basically, my view is that so long as you can get away riding with 1L of fluids, this is a no-brainer, cheap as hell aero upgrade. Frankly, these are so inexpensive, that it's almost a sin not to try them, even if you end up only using these part-time, given all the other stuff we are discussing on this forum and the $/watt or $/gram saved ratios. If/when you need more capacity, then it's back to standard bottles, a more expensive and ugly Xlabs bottle, or a behind-the-seat option.
