No provision for caps to lose, how will some people cope!
It seems to have been designed with ease of use for tubeless in mind, both adding sealant and increased airflow to stop it clogging. That may also be an advantage to those who wish to use sealant in a tube, I may choose to do that at some point, but until then I don't think it offers me anything. I have in the past bent pins an Presta valves, but only on high pressure tyres using a direct fit mini pump. Since moving on to wider tyres and the mini track style pump, it's ceased to be an issue.
Also, I can't see an easy way to release air? That isn't an issue on any of my current bikes, though on some previous ones I've had to deflate to remove the wheel.
