That is mainly because quartz coil atomizers have a coil wrapped about a quartz core and bits of dried-up residue can get stuck involving the coils. Considering that the coils are so close with each other, it can be hard to get rid of the residue from them. The bowl-style atomizers do not have that difficulty due to the fact they are just a smooth, even surface. So, if you want your vape pen to be as low upkeep as achievable, you should really look at 1 that has a ceramic or quartz bowl. You could possibly even locate that they have other attributes that you could possibly like.
Examples of coils-significantly less vape pens are the KandyPens Crystal (Critique | Invest in) and the Linx Blaze (Critique | Invest in).
