Did you buy them from 3fvape? Also if you did, did you get the 12.5mm or 12.8mm ones? Additionally if you got the 12.5mm how do they fit? I know that’s a lot of if’s But I was just wondering if the 12.5’s fit nice. Judging by the 12.8’s I’d assume the 12.5’s should fit perfect but I’d like a verification from someone who’s actually tried them.I bought some of the heat dissipators but haven't used one yet. Since mother my Zesthia and my Manta tanks don't come with 810 to 510 adapters, I have stocked up on those. I will give a heat dissipator a try since I used metal DTS and that just might help. Thank you!
