My Gen 3 still works after six months of daily use.
But.
The Black paint is ruined, the display has become too dim, and the mod is providing much less power to the atomiser than when it was new.
So I retired it.
Junk or not junk dilemma. The general low quality is not limited to Wismec, the middle priced devices are not designed for longevity, so that drop in functionality, or the complete failure altogether, is to be espected in my opinion.
The replacement for the Gen seems of better quality tho.
