This is without a doubt one of the best vape kits. It fits comfortable in your hand and vapes Great. “TIP” I smoked over a pack of cigarettes a day. Ive tried Nicotine patches, RX Pills and nicotine type mints. Nothing worked. Ive had this mod kit for 2 days and haven’t even thought of a cigarette. I got only 3 mg nicotine in the juice I selected. If you tried everything else like I did try this. I promise it will help.
