Someone asked about passthrus destroying computers, and I have not actually used one myself, but I would not recommend it. The first website I was referred to for e cigs and ordered from was My PV shop, and not only do they have a big, bold warning in several places on their website, but they even send one with every package you order from them stating the danger of using PTs with a USB port. However, most places that sell PTs also sell the AC/wall and car adapters for them, which are perfectly safe to use, and I think the combination will be my next purchase.
