Sorry I have not tried/used it, but have been eyeballing their
mod section. I want to try building my own. If you do try it out I'd be interested in your thoughts on it.
Out of curiosity what kind of mod you looking to build?
I've got my heart set on my own tube mod, vv with display. Spent 4 hours searching electronics suppliers/manufacturers just to find the activation button I like.... gonna ba a loooonnnnnggggg process for me, as I have to learn as I go and am picky as hell.
