I like them both. Its nice being able to have your hands free while driving, gaming, cooking, whatever. But for me my manual batteries last all day. The Autos I am lucky if I get a couple of hours on them. When I am out and about I usually have both on me. I usually use the Auto until it dies and switch to manual mode. If it is your first e-cig and you can't afford to buy both go manual. They are easier to care for, last longer and way more dependable. Personally I think if I supplier was being creative and wanted to differentiate themselves they could include both in their kits.
FYI... cignot.com you can pick the battery. I recommend to everyone I try to get to try vaping to order their no box 510 kit and if they're not sure, you can pick one auto and one manual.
