I forgot how well my SE actually worked until I received my new atty from Totally Wicked..
I would buy RN4081 again if I could find a good price in the USA.
I really kick the 4081 attys, only dripping. 2 months and killed 1 atty after the first 3 weeks. Then another one died together with a new battery (remained on, killed the atty and the batt). For the last 5 weeks am using the same atty with a nico box with 14500 batt and USB connector for home. Still have ~15 spare attys.For the price I paid, anything more that 2 weeks in atty life I consider a bonus.
For cleaning I burn the atty to red when on USB, around 5-6 times /week when I feel like cleaning it.
2 drops are around 1 cig for me. Never put more than 2 drops if using the original battery or store bought USB pass through because 3 drops are putting the batts in danger of getting soaked.
I never let the atty cool down, sometimes I vape constantly for 30 minutes (yes, it's always hot).
On nicobox mod I use 3 drops and go through around 4 to 6 ml/day. PG liquid or a maximum of 20% VG mixed in, my attys don't like VG based.
Using just the empty cart that is on the atty by default.
