maskgeek - When I first started I needed SIMPLE and I was still overwhelmed. I stayed on this forum for a few months trying to learn all of the little tips and tricks other members had experienced. This was after trying a two-piece job that was horrible and not worth the money spent to send it back.
Then I got the 901 and now I have the 510 and I really like them both. However, I have turned the 901 over to my DH and we will see how it goes with him. I think the 901 is great to get your feet wet, so to speak, and the 510 appeared to be the next obvious step for me, since I can't get the mod I want until later this year.
I do find that the 510 has a warmer, smoother vapor and I like the control you get over your vaping experience with the manual. I also heard from one of my favorite suppliers that they are getting ready to rollout the 901 manual battery. I am so eager to try this out.
Best of luck.
