“My last 3 packs have been terrible. They have been burning out really fast. They're only lasting a few days then the coil stops registering with no warning. If it carries on I will switch to a different brand.”
“Not very well made and quality varies from coil to coil. 3 out of 5 in the box have don't have enough wick material inside and have burnt out quickly! Unfortunately, this is the only coil type available on ET for my T18II.”
