First the fireluke mesh which most reviewers raved about (I have one). Then the falcon mesh which, per most reviewers, was better then the fireluke. Then freemax came out with the mesh pro (which I also have) with the double and triple mesh coils which most say is better than the falcon. In September horizon tech will introduce their double and triple mesh coils. Just to top everything off innokin has just came out with a mtl mesh coil. In my opinion the winners in all of this are us the consumers, nothing beats competition.
