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

This isn't the worst heat sink I've ever seen but it's definitely on the rougher side of things. The channels cut into the top have surprisingly sharp edges as does virtually every other edge on it. There were some down right razor blade filings left in the channels around the fins as well as some really rough machining around the pin on the inside.One big thing to take note of about this heat sink. The pin is very long and while with some pressure you can move it up and down it is still generally going to be too long for most tank/mod combos without first grinding or filing down the pin on the bottom beforehand.Other than that it does it's job. Just know it'll take a bit of work when you get it.

Brass pin to short to make contact with Mod.

I figured that i would have issues with it when i ordered it because lets face it most amazon stuff isnt great but this did pretty well.

Exactly as described.

Amazing!
