if u are hesitant about manual batts.............get one of each to start. I thought I wanted the auto but after reading here decided to go manual. Felt a little awkward at first but within a couple days becomes second nature and you don't even think about it. No regrets about skipping the auto; no primer puffs just push the button a sec before first draw and get good even vape as long as you have enough juice in the cart.
