Actually all of JoyeTech's products are clones of other company's designs- pretty well all JT products were designed by Janty and Ovale.
As far as competing brands- Kanger, SLB, Vision, etc are very large companies and all make very good products. Right now I'm leaning towards Innokin products as they seem to be more focused on quality than competing brands.
Did you realize the "CE" that is on products from China is actually not sanctioned by the European Union...it's a knockoff LOL. No one in China will take responsibility for the CE logo but it supposed to mean "China Export". China= land of Patent infringement without penalty.
