“I love my Endura T 18 honestly though I will not order these coils from you again as 4 our of 4 were toasted in 1 to 2 days by the fifth one it was finally a lasting coil . We tested them on my buddys tesla mod on 14 v 1.5 ohm and resistance just shot up after a day too two days not thrilled. I will buy products from you but these coils are not good , not sure if it is you or Innokin on this one but there is an issue with these coils frying hit after hit. Honestly when the ohms our higher or the volts are dialed down on a different mod they are great the T18 just cooks these things. I have noticed if you lay the t18 on its side and never use it stand it stops happening and the coils do not get cooked as fasted . I think there is a das boot effect with the stand are bubble at the top no wicking fried hit fried coil. I love you guys but I am not completely sure these arent the coils from the i30s taste like silica when they burn”
