Ya tried it- blocks my liquid all together when i turned it upside down. Dry hit blah-Im good Little liquid on top of the rubber thingy is fine with me- Ill deal with it- Im vaping Gambit so nothing else matters right now! Hehe!
My oldest ones are 8 months old and no signs of quitting. From there the dozen or so are anywhere from 2 to 6 months old...same thing. I just use one for around the equivalent of 6 to 8 tanks full then throw it in a "to be cleaned" pile whether it seems to need it or not. (I use pretty light juice.) I clean the bunch when I accumulate enough to set aside time for so they're always in rotation. I usually pay $22.00 for 5 so at this point that's 55 cents per month at the most and will be less whenever one quits. Also they're super easy to rebuild so the cost of wick and wire is all I'll be spending but I'll have Hubby do all that.
The 2.5 ohm heads need higher voltage. The 1.8 ohm heads will work good around 3.7-4.0 volts. You said you have and SID. Isn't that a vv/vw device? Why aren't you using the watts setting and letting it set the voltage for you. You should not be going through heads that fast. How hot are you trying to run it?
You might try cignot or litecigusa.
