sigelei 30w

[cleggjm]

I saw a review for the segelei 30w. I think it's a good upgrade from the mvp 2.0. Just want some feed back on it. What type of batteries should I use for it? Are there any other mods that you could suggest besides this if this one is now worth it. I believe that this is a good gateway to mechanical mods and to start building coils.
