Gold plated center pin is nice. Quality is there, I just wish the edges on the fins were taken down a tiny bit more. Sometimes these can get stuck in your mod and you really have to grip them to unscrew them. Well, they are a tiny bit sharp still. They aren't as bad as some, but still a little rough, imho. That last feature would make these an absolute steal for this price.
I use this for a wax atomizer that auto fires for 30 seconds. It'll let me hit back to back if I wanted to.

These are really useful when using 510 mods. They do have a tendency to heat up, heating your box mod along with it. I consider these essentials so far. You may find them on DHGate, or Amazon as well. I'd trust POTV and these will get to you within the week.
It worked as intended it has good threads. I had two generic ones that had bad threads
Does what it's supposed to, very helpful for collecting the heat instead of dispersing it to the battery or atomizer
