Carry-On Vocal Booth 1.0:

Yes, I was able to carry it on the plane, though sometimes they made me leave it for the ground crew to load in before boarding (I didn’t have to pay for it to be checked though.) And while traveling by car, it actually doubles as another partial suitcase, which is pretty handy. I really like how thin it is.
All in all, it was a nice solution and did just what I needed. I even got the job for one of the auditions I did while I was away.
That said, I used this on my trip, and it actually worked really well.
I’d certainly recommend your product.
