This is by far the easiest replacement of a coil of ANY of the systems I've had! All you do is remove the tank, turn it upside down, slide out the old coil & slide the new one in! 4 short movements & less than 10 seconds of your time!! They last a while too, so there's less need to change. I highly recommend them, along with Vape UK.
