I'm a huge fan of the ipv d2. Been using it for the last few months and it's been great. I swap my thundercloud rda or the tank by the vapors on there and it's a really smooth build. Also works well with the cloud champ plus and and aspire triton and the praxis tank as well. Huge fan. Again, like earthling mentioned - battery type is very important. I'm extremely paranoid when it comes to some things and vaping certainly is at the top of the list. I'm a huge fan of the snow wolf mini and the sigelei 75w is my latest pickup. But as far as size. The ipv wins hands down when it comes to size, button "clickiness", and adaptability. Enjoy!
