Shenray used to make their own products, but according to my source have been reselling others' products since late 2019. doesn't mean Wejoy is their only provider....some small shops probably still exist to do "spec work", or "overflow" from larger, busier companies.

One thing for sure: Ulton, SXK, and Wejoy make great products, and do a pretty good job of filling the niche void. Anything we get from any other company, especially YFTK or Coppervape, is a bonus. the industry will continue to "streamline", unless a "revival" of sorts takes place.
