Awesome to hear, but I really cant wait to see what you think about both and which one you find to be the better of the two. Since Im trying to figure out which to order next.
Final Update:
After Vaping all day with the SD MKII, i feel as if i can accurately give an honest opinion.
- The Tornado is an amazing PV. Excellent Vaper and small enough to fit in my shirt pocket for travel. The SD MKII isn't as big as i thought it would be, (definite plus) although its not as portable as the Tornado. I'm not sure why the MKII comes with a stock 901 Atty. Although it produces great Vaper, in my short experience with it (about 3 hours), every 5th hit was very weak. (this could be due to a new atty)...i threw on the 501 adapter and Low Res Atty......WoW, what a difference. Absolutely solid, and i mean solid Vape right from the start!! (i cant wait to see what it produces 3 days from now)
The Tornado is a very solid build. Small and Tight....very concealable. I don't foresee any body problems in the future with normal use and good care. As for the SD MKII, not so much. The spring/cap does come loose, and could be easily lost. I had to tighten it 2 times already. (and to do that, it has to be disassembled.) I did put on the Cap Lanyard as I stated before, to keep the cap close by. If the cap gets lost, look-out

, cause it takes zero effort to activate the atty. (which is good and bad IMAO). Reading other posts, it seems the SD has to be well cared for...weekly cleaning etc..
The SD MKII gets better vape than the Tornado with the 501 adapter and LR Atty. Stock, the Tornado hits better.
Verdict:
At Home Device - SD MKII is the PV to have w/ the 501 Adapter. I can see this to be my PV of choice while driving as well.
On The Road - Hands down, The Tornado will be my Vaping Machine. Produces a lot of Vaper for such a small PV.
Hope this helps. Feel free to send me a message............
