My dabado m just came it and i screwed in the quartz nail and it broke. I was at least able to remove the threaded part so i could use the ceramic nail. Works good so far on my rx200.
I got one similar to yours but i heated it to much and it made me ill for like a week. I think it was releasing teflon gas. Also got dr dabber quartz nail for it and it didnt fit. Im tossing this one lol.
