If you're new to this, start with a device that has adjustable wattage. That way you can experiment with different power levels and see what works best for you. Dual mesh coils perform well at moderate wattage, so you don't need a huge battery to enjoy them.

One thing to watch out for: not all dual mesh coils are created equal. Cheap ones might have uneven mesh or poor connections, which defeats the purpose. Stick with reputable brands that have a track record of quality.
