These are great coils, I bought 3 each of the 0.2 and the 0.6 as I have had great success with both these coils. I will most likely in the future get the 0.2 ohm coils as I am a lot more comfortable with the lower ohms now. That said, when I found these coils I was elated as I really, really like the Vapmod Xtank as it does hold a whopping 10 mls of ejuice. Now that I know I can find these coils I will use my Xtank a lot more often now. A great find for me, a great find for anyone who has one of these tanks, if you don't no worries you can get yourself one of these tanks at this website. The .6 ohm coils doing superbly in giving the vaper the flavor that we all look for, as we all know taste is extremely subjective, but this is where these coils in this tank make it equal in the flavor department. The .2 ohm coils are great for those of us who like bigger clouds, the .6 do well in the cloud dept but as I said flavor is where it that coil shines. Clouds is the job of the .2 ohm coils and it does a fantastic job with vapor at least for me it does. I cannot remember what the highest wattage is for these coils but they are well made and can handle some decent wattage. Truthfully anything sub 100 watts is probably where these babies lie. Thank you all for reading, be well, stay safe, God bless, and....VAPE ON!
