No, I do not receive a commission nor am I a representative of either of these two microfiber sellers/distributors/wholesalers. I have not purchased products from either of them, so I am not even a good customer. Like the original poster (OP), most of my stash of microfibers comes from Meg's over-the-counter or Target's detailer microfibers (I think the name was VROOM, but Scottwax, at one time, said they were OK) or the bargain microfibers from various places (Name brands like Rubbermaid or Peak), so Yes, it is time for me to upgrade.
I do have a microfiber towel I love: it's the red microfiber towel that came with AutoGlym's HD wax that I bought on closeout from Wal-mart (where else!?) THAT is one great microfiber for removing wax and it's relatively soft. Last I looked it was about $8.00 US plus shipping; not exactly cost-effective by my standards.
The above linked microfiber resellers are gleaned from posts about their products and service found within this forum. The fact that some of you Autopian professional detailers (who I have the utmost respect and admiration for) can vouch for their superior products and service is reason enough to let others know about such resellers.
