Yea I am in the new members forum gotta get my 5 posts in before I can come over and say hi. I have been reading a lot in there but wasnt able to post.. I think I am at my 5 now.. lol.. So I just need a multi meter to check ohms correct.. How often do you have to rebuild or put a new wick in there?
Yeah, I saw you were at 6 posts this morning so you're good to go!
The multimeter checks your coils resistance, checks for shorts, and checks your batteries charge. It does more, but that's mainly what I use it for. Its really a must have unless you've got a mod with an ohm check or a 510 ohm checker. If you get a short, your spring will collapse and make your REO out of commission until you replace the spring.
Rebuilding varies from person to person based on preference. I've heard some people run the same coil for 6 weeks (or more), I usually rebuild mine every couple of days just for fun. The wick depends on what juice you run but most people get at least a day or two with sterile cotton for wick, it is super simple to just pull out the wick, insert new wick, squonk, and vape (takes maybe 1 min tops).
You could also run silica wick, it will last longer between changes but when you change it you'll need to make a new coil as well.
