RAYEE 510 Finned 25mm Heat Sink Adaptor for Atomizers (Silver)

I recomend it for use with 510 tanks as it helps keep everything cool after use which stops the tank heating up the battery and also the tank itself if cooled down quickly doesnt leak as much or cause other problems. Also It can be used as an adaptor to allow one to put a tank onto a hybrid mod due to the need for a protruding centre pin (though double check it thouroughly before actualy doing this)

I didn't really buy this as a heatsink - I don't generally vape at high enough wattages and temperatures to make that an issue. It does do a great job, however, of stopping me stripping the threading even further on my Tesla Nano when I'm constantly changing tanks for different flavours.So for that, at least, it's working exactly as intended.

Threads arrived with damage and tanks flop about during screwing in. It does work well once tight, so I haven't got too much to complain about.
