I started with a SiD and got an MVP2 as a back-up. The Sid died after 4 months and I got another MVP2. I have others and my IPV2 50w is my hottest. I tried power with it and it was not noticeable other than a warmer taste. I have a couple of others, but my MVP3 is my go to PV. The MVP2, my wife still uses. They are durable and the battery still does fine for all-day Tootle Puffing. I do like my rDNA for it being smaller. Sad to say, my iStick got thrown in the trash because it was just made cheap, in comparison. I read and notice what mods seem to have trouble and, what is best for me. I wish more mods had colorful sleeves, but, to each their own.
I used to put a lot of money, more than I did cigs, into mods and toppers but I have slowed. I have done a lot of PIFing. I have a couple of RDAs, but my Lemos are simple and give satisfaction.
I am very happy under 30 watts.
