OK, I got my V2 from Zen himself in a trade for an Opus V1. So here is the skinny... I THINK IT IS GREAT!!! I don't know about making cartos tase better but I think it might a little bit. I am currently using Boge laser punched cartos from litecigusa.net and my juice stays pretty tastey. A couple of things got me, one, the bottom switch does not lock. If you back out the switch before putting it in your book bag it wont miss fire as it will back out 3 1/2 times. Another thing is that the tank is made of fused quartz, standard and as many of you know, fused quartz breaks more easily than other tanks. I went ahead, after I knew it was a keeper, and ordered a tall and short borassilic pyrex glass tanks from Ibetanked.com . Well I have had it for 3 weeks now and I just bot a Killer 705 rba and I am going to report back here to let you know how it goes. I've heard it is a great match so I'll see. I do think the ease of just screwing a carto down and filling it up, the right way, is great for older (47) shut up.... people like me to get a great vape and do it in style. Many people have asked me where is my ss wick... No fussin' with ss wicks here, just good vaping. Oh ya, I have been using a Kick V1 at 10 watts with my 2 0hm Boge cartos. If you have any questions just PM me. I will report back on the Killer 705 and the different 0hm coils I try and and any other questions you have, Take care and I'll be back soon. daze
