Like everything in this world, I think it’s situation dependent.
I traveled for work, and would live out of a hotel room for 4-5 weeks at a time. I have a gaming laptop that doesn’t fit in the bin while going through TSA. Always got comments about it. But damn, if I didn’t love setting it up in my hotel room and leaving it there during my tour and being able to play some games during my evenings.
It was WELL worth it!
I do not have a water flosser, and asked this exact question to my dentist about two weeks ago.
Turns out, I could’ve asked you! As your answer was EXACTLY what they told me.
