I have never bought anything from ft that I could not find something positive to say about before but these coils are terrible. The first one I fitted was left to soak up juice for thirty minutes but still gave dry hits and burning taste.Left the second one longer ...same results.After reading the forums I tried removing the wire gauze and priming the cotton with a little juice before fitting.Thought this had cured the problem but then after a couple of hits bad burnt taste followed by complete coil failure. It may be that I have been sent some from a bad batch but I will not be buying these again and cannot recommend them.
