Is that the generic plexo pet from China? Its not very good quality IMHO. Its very thin and has a flat profile and doesn't hug the cable well.
I got it from Hong Kong. I just tried two pieces out on a cable I have and it hugs pretty well. It's a hair looser than I'd like, but it's not bad at all, especially when I pull it tight like I will be when sleeving with it. It has nice coverage too and you can't see through it to see the cable underneath. I'd still put it behind Kobra, Bitspower, and MDPC-X in quality because it is a little thinner and hugs a little worse, but not so much that I wouldn't use it for my own cables. It's not like the cheap generic PET sleeving that looks like trash and it's far more consistent than paracord.
And I was debating saying anything and since I really don't want to cause drama, but should you really be making comments like that given the nature of your business? It comes off as you swooping in and trying to scare people away from someone since it might take a little business from you. If it helps soothe your concerns, this isn't something I plan on making into a full fledged business or even a long term thing, it's just as a way to make a little money while unemployed and looking for work. It would be better to ask what I thought about the quality since I will respond honestly.
