Not knocking the expensive, cool tanks at all, in fact I'd like to have a few. But, my cheap Smoketech DCT tanks work just fine. I have never had a leak or a problem with them. Their easy to clean, fill, and change carto's. The thing to work out is the carto's you prefer and the your method for getting juice in them. For quite a while I just bought the pre-punched dual coil Smoketech cartos - most had three small holes. Had mixed results with these. On a whim I bought some single coil standard resistance Boges un-punched. I slotted them per PBusardo's video and what a difference that made. I had no idea what I was missing before. Good luck with whatever juice system you choose.
