Very partial to Evods here. I'll prob invest in some pro-tanks soon but I have a nice rotation of evods going with virtually zero issues. I tried a top coil clearo and hated it. Too much hassle. I'm sure there are ones that work fine but they weren't for me.
I like my stuff to be simple, easy, and reliable. I also like the airy draw alot. Evods are simple to fill, clean, and the heads are a snap to clean too. I can squeeze 3 weeks of vape time out of each one before I toss them. I'm too lazy to rebuild.
