@Renor – I own the Swag, great little device that is very well build. Are you planning on buying the kit with the NRG SE tank or just the mod on its own?
The Swag is limited to 22mm tanks or smaller, so the TFV8 Baby Beast will fit. However, the NRG SE tank is just sooo much better in terms of build quality – fit and finish are great. Both can use the same type of coil so performance based on the same coil will be pretty close to identical. Also keep that 22mm limitation in mind should you wish to change tanks – especially if you are looking for larger juice capacity.
The Swag is a single 18650 device which does come with its limitations. If you prefer to vape at higher wattages, 50+ per say, you would enjoy a much better battery life with a larger, either 2x700 cell mod or dual 18650 device. But outside of that, it is small, fits great in the hand, excellent build quality and functions very well.
