I thought I was the only one with isticks anymore. My first one (20W) has stripped 510 threads...of course.
Then I have one 30W that either has a bad battery or the board is failing or bother. Haven't used in probably 2 years. And 2 more 30W still sealed in box.
I still have the first 20w I ever bought. Still works fine, but I don’t use it much. I’ve lost a couple, dropped in the pool, one started auto firing. I think I have two, and a 30w.
