I can promise that "lysen", "vazzling", "marstech", etc have never made an atty. They do, however, distribute WejoyTech's products to various resellers.

Your favorites are made by the same company. Kinda makes sense, I bet!

I know that ShenRay is alive from correspondence yesterday. They, too are simply buying Wejoy products and reselling them.

Most "clones" that are not SXK, but are 1 to 1 are made by Wejoytech. Ulton still makes products as well...YFTK and Coppervape are two small independent manufacturers that I can't find out ANYTHING about, lol! I do think they still make their own products when they are able....but I can't know for sure.
