The multi-mesh design really does make a difference. But, if you’re looking for something super convenient without worrying about coils and all that, I’d recommend trying a Packman disposable. I switched to one recently for my on-the-go needs and it’s been a lifesaver. No need to carry extra coils or worry about recharging. Plus, the flavor is pretty awesome. Have you tried them before? It might be a good backup for those busy days when you don’t want to deal with coil changes.
