Sewell Ghost wire


Hi all. I asked this in the Home Theater forum but got no response. I wonder if anyone has any experience with or opinions about Sewell Ghost wire. It would be handy to use for ceiling speakers (for Atmos), but I wonder about it being (I believe) 23 gauge. The runs would be about 15 feet.
Has anyone used it?
Thanks.

As I look further, I see they also make a 16 ga. model. Still interested in opinions.
