The first device we recommend that has a proven track record of helping smokers make the transition is a closed e-cigarette, such as the alt. pod kit or the HAIZ Pod kit. Enclosed vape systems are very easy to use and are the most successful way to transition from cigarettes to e-cigarettes. Alternatives. and HAIZ products offer smokers who quit smoking a similar level of satisfaction as smoking, but without the thousands of harmful carcinogens contained in cigarettes. These devices all contain a battery and a pod (filled with e-liquid), and that’s it! Simply insert the cartridge into the battery and vape – no batteries, no mess, which makes it an ideal and first option to consider when buying your first vape.
