I have a 100w plus with a Doge 2 on it. I have been using it for about a month and I am really happy with it. A friend has a ipv2 and I tried his, and I was sold on the box mods. Thing hits harder than my copper mech mod without the constant maintenance and carrying extra
batteries. The dual batteries really sold me on the Sigeli. I work 14 hours a day. And they last 2 days running at .2 ohms. I want to try some higher resistance builds and see how they work out.
