Well as Snowdragon already pointed out, we have a new product available today. It's the OMG All Day. This is a 3.7V (4.2 fully charged) Mod with a 1500 maH battery. That should give you all day vaping on a single charge. The OMG is KR808D threaded so all of our existing carto's and tanks will work with it (except the 510 tanks). We put together a special package to launch this product. You get the OMG Mod (available in Black, Blue, Yellow, and Pink), 1 18500 battery, charger for the battery, 2 6ml tanks, and a 30ml bottle of juice... all for $65. That's a deal that's tough to beat, so no other discounts will apply to the OMG All Day. Get yours today!
