Actually, EmpireMods attys start out great and IMO have diminished performance later. Oh, and don't hit them above 3.7 (maybe 3.8v max) or they'll be fried; also I never recommend dry burning bridge free attys (don't know why, but they seem to be less able to stand up to it). That is my experience with them. They hit great to start with tremendous flavor and performance; but that doesn't last. After a short while I always got reduced vapor output (whispy vapor), easy flooding (the mesh seems less absorbent), and more frequent dry hits. But once again, from jumpstreet they were all great.
Were you vaping on a VV or VW? What volts or watts did you have it set at?
+++++++++++++++=10 on that for sure
