Well with two of those, you would never have to worry about a broken PV again.
They very, very rarely have an issue. If they do, a year warranty comes with the purchase. Even after the year, service on it is fast and cheap. Usually it is back to the owner in a week, and costs 20 bucks. So instead of a pile of broken eGos and twists, you could have a couple of battle tested, first rate mods ready to take care of your vaping for a very long time.
