Have to send kudos out for DiscountVapers! They have some items that you just can't find anywhere else, and their prices are great!
I got a couple button covers from them, CHEAP. Don't have to worry about them firing in my pocket or purse now. Burned up at least a couple cartos that were just filled. Really sucks when you fill a carto and think you're set for the day and end up having an empty, burned up carto when you get where you're going...especially when you didn't bring extra cartos or juice. *UGH*
Also got some clear cartos. I have been curious about some cartos that just aren't hitting, but add a bit of juice and they're overfilled. These allow me to visually see what's going on. A lot of this has been the batteries I think. The carto I've been vaping since last night was barely hitting with the old batteries. Put on the new battery and getting plumes of vapor!
I was tossing old cartos when they wouldn't hit properly anymore. I had tried to disassemble, clean and reassemble. A lot of hassle that I decided wasn't worth it. I'm going to try just rinsing them now, because I can see blackened buildup around the area that gets heated in the clear ones. I rinsed a clear one and it cleaned up easily. Let it dry 2-3 days, filled it and it's hitting like new! That I can do. I'll get a bit more life out of them just rinsing, and it's easy. I smoke darker juices and I think it gunks them up quickly.
The clear ones seem to have a heating wire that goes up the center tube which I don't think the regular cartos have. That's what helped me see the gunk building up around the heating wire. I'm really glad I bought some. It has helped me see what's going on, and I'll be saving money rinsing cartos instead of throwing them away prematurely!
Always learning more about vaping. This community is great, and so are most of the sellers!
