btfc rda

My original BTFC RDA arrived with machining issues but it still worked. So the company sent me a replacement BTFC RDA with perfect machining. However, the new RDA is reading "Shorted" and between .02 and .03 with no coils installed. And with coils installed (brand new claptons) it also reads...

Just got the BTFC and 3 out of 4 grub screws are stripped. When applying even light tightening the Allen key just spins and spins. Are BTFCs known for very lousy grub screws? I applied very little tightening ...just to snug. If so anyone know of a high quality replacement & grub size?

So excited to get my BTFC from MFS today only to find the post holes on one of four posts we're paper thin. Hopefully I can get a replacement so dissapointed.

Okay so I picked up the BTFC. I like it but the airflow not so much. My previous RDA used for squonking was the Drop. I generally run 2 coil builds with my Topside Dual. I vape between 80 and 140 watts depending on build/juice/mood. I'm looking for a new RDA that is fantastic for squonking...
