510 Stainless Steel Heat Dissipation Heatsink (25mm Diameter, Rainbow)

This is precisely what I wanted, a rainbow style heat sink with the right diameter to match my rainbow Cerberus tank and more importantly, my rainbow Mig Vapor Sub-Herb ceramic tank. The ceramic tank gets pretty hot but this sink does an excellent job of reducing the heat transfer to my mod battery case. Arrived within the projected delivery time, does take a while, but I was in no hurry.

Wont make contact, mod wont read atomizer. Even adjusted the screw, its just off just barely. Black one i ordered worked perfectly. Kind of disappointing.Edit/update: great customer service responded quickly, sent me a replacement and a gift for the mistake.
