I'm puffing away here as we speak. This is my very first experience with a Manual switch. I am PLEASED! (I did a devious thing, I already had my order in when I asked for you "salesmen" to step up!) I do believe the vapor is better volume-wise, a little more predictable and constant..I just switched out the atty from the Auto, and the battery which I just changed, so will be curious to see if I am saving battery energy, which I think I may, and learn to not scorch out my cart by holding the switch down too long! Three second hold is just perfect for me. Also, I do think the vapor is maybe a tiny bit warmer, so my JC Original tastes a little more flavorful with the Manual. Haven't tried the JC Tennessee Cured yet. So far the timing for burn and puff is pretty easy to master. I had a little issue with the automatic, the cut-off was a little too short, only about 2 seconds, so had to do two or three puffs to get sufficient vapor. But Janty kindly asked me to send it back to review that one, see what the problem was (I did think it was circuit-board related). After a few days it started doing some burns on it's own, so was a little worried about that. I have returned it, will be anxious to hear what the verdict was. They were absolutely 100% behind me, the user. So am very glad for all of your help. As time goes by and use of the Manual proves to be consistent, will be more than happy to endorse it, as well. JUST A NOTE: I did buy an auto each for my daughter and her husband, so far those are working perfectly, don't know if I'm going to tell them about the Manual, just yet! AND: I received a BOX with this one. Well, it's a nice box. My order #4989
