Working great so far. Hope it holds up
Best pen, I have 4. Reliable better than more expensive ones I have bought.
Loving this battery!
I bought the battery to replace my old one that was my starter battery. This battery achieves a way lower heat up temp and the flavor is just incredible. I only use profiled cartidges, so I didn’t need the full kit. So I just came here for the battery. Fits all of the standard 510 tips.
