Where as the main unit is pretty loud, it generally is not a problem in most social environments. I
have seen it performed live from about twelve feet away in a fairly quiet bar and did not notice
anything. I know own Vapr and I am most pleased with it. Everything has been beautifully designed
and works amazingly.
The best part is not only the remote feature, but the cartridges can
be easily refilled using simple Glycerin found in the first aid section in most Pharmacies. I have
not had a problem yet.
I would love it if they could come up with a way to color the
smoke, but this is the highest quality item I have ever bought from a magic shop.
