I received the 2 replacement V-one XMax atomizer coils to have as back up for the original one I have and I still haven't needed to replace the original one yet. These atomizers last quite a long time and I get the best flavor from it. I highly recommend picking up the V-one XMax setup and getting a few extra atomizer coils for backup. I only have a couple things about it that I don't like and that's how the melted product ends up under the ceramic donut atomizer coil and ends up burning up wasting your product and I don't like that you can only put a very small amount at a time in the "bowl" or you end up flooding the coil and burning your product. Other than those few things I absolutely love it.
