Need to keep an eye out on the new Loast Vape drones. 510 connector issues new out of box. Sent to Evolve for warranty repair and what I got back is the same as I sent except now the centerpin and 510 connector has gouges in them. Repair work looks like it consisted of someone using pliers and pulling the pin up. After placing rda back on after repair everything went right back to how it was out of the box new with the centerpin sitting very close to the threads. Looks like I have a new paperweight
