It's more convenient to not have to worry vs your current tank but a drawback is it might seal air tight on some mods with the locking ring. It did so on my Vamo, but I cut a slit into the ring and it fixed that.

I have a few of them along with a few standard tanks. I enjoy them both but they feel exactly the same since I use the same cartos in both.

Another thing to consider is the extra step to filing being removing the bottom ring.

In the end it will come down to preferences.

There is no one best tank for everyone. What works great for me and my juice, may not work well for you and your juice. Like Ghost said it all comes down to preference. I have alot of different tanks/clearomizers. Ce3/4's, Vision Vivi Nova's, iClear30's, kanger Evod's, Protanks, F16, AGR Locking tanks, IGO-S Dripper, AGA-W RBA (starting to hate this one, probably gonna sell it)

It all depends what i feel like using and what mod im using at the time. If im doing yardwork, im gonna grab my bolt with F16 tank or mini mode vamo with a Evod. If im watching tv or sitting here staring at this screen posting vaping stuffs, im hitting the Itaste svd with 6ml carto tank on it! It's all subjective, just like the best juice!

Get a bunch of different ones, stay on the inexpensive side until you determine what you like. I think i'm in the spot where i might be buying a more upscale carto tank in the near future! Just cant decide which right now.

There so many online stores there is not much room for profit margin.Brick and mortar is where its at right now with the online to turn over product to keep it fresh.The only other advice is sell brand name products people can identify.All of us on the forums tell people to stay away from places that try to house brand things .
