I purchased a ikenvape 510 1.5 ohm atomizer at the end of last year. I didn't use it until last week and it didn't even last a week but I purchased it over 2 weeks ago so no warranty now. I used it on my reo grand with the 4.8 volt battery. I kept it wet but it died today. When it broke in I had good flavor but not much throat hit. Has anyone had good luck with these? Was I running it at too high of voltage?
