I have that same mod. Most vaporesso tanks look great with the tiny Nugget mod. I found them a few months ago and they kicked the other tanks I have out the window. I'd suggest the "orc" tank or the "gemini". They fit and have cool features. To fill the tank unsure the top. Changing coils, remove the tank hut leave the connection ring on your mod. Removed the coil and replace it. Now I know there are other top fill tanks out there. Between my hubby and I we've used them all. They can be difficult and if not used perfectly they tend to leak (that's just my experience).
The absolute best feature ever is that there are a ton of coils you can use. There are lots of CCell coils but you can also use aspire coils. I use both. Also for some reason the aspire coils last a very long time as apposed to using an aspire tank. 3 and or 4 days. In the Vaporesso tanks they easily go 10 days. I've forgotten when I replaced the coils.
There is one thing I hate. The tanks still spit juice. When reading about them they all say the tanks don't spit. We'll, I'm currently using 5 of their tanks and all five spit. These tanks also allow you to adjust how much juice they burn per hit. I leave mine wide open.
That's only a brief window. Yes, I could easily add more relevant info. Since I wrote a novel answering this question if anyone has any questions by all means ask me. I'm happy to share more.
