I have a number of flights coming up in the next few weeks, including a couple to and from the US and will report on how things go.
Don't expect consistent experiences. As said it's plastic so won't set off metal detector - so when I go through I make sure it's in my pocket, and usually they don't notice the small tube, or wear a shirt untucked to cover it.
Easier than volunteering info, explaining, answering questions etc.
