Well, still no tracking info is available for my istick. That's ok though cause I got it yesterday. Found it in the box this morning. Shipped Monday and got here Wednesday. I have tested it on a few toppers to see how it performs. It seems to burn at anything over 10 watts except for an iClear X.l, as I expected. Tanks won't sit quite flush on it but the adapter does. Here's what I found so far
Rose 1.3 ohm single coil- fires 7 to 20w won't wick fast enough over about 11 to keep up
Joyetech 1.5 510 atty- fires 7 to 20w best below 10
iClear X.l 2 ohms- best below 10
Kanger T3S 2.5 ohm- best below 8
These are my preferences with the particular juice and coils/wicks I have in these. I haven't taken the time to find the best settings for the different devices but I don't understand why some say that adjusting at lower settings has little effect. I found a sweet spot at 6.3 for an apple that was in one of my wife's Kangers. I like the .1 increment adjustment for fine tuning. It's small and easy to use. I don't see any problem with the threads especially using the adapter. Screw up the adapter, replace it. I think she will just be using the iClears on it for now with the adapter and beauty ring so I don't foresee a major thread issue from swappin out different tanks. She usually only removes a tank to fill it and that's it. She has the same 2 Kanger tanks I gave her a year ago with the same coils. They never leaked, gurgled, flooded, nothing. I had 3 from the same batch and had all of the above. If using means means longer battery life then by all means keep it. I don't know if that's the case but I still have no problem with it. It's easy to adjust to it. The best thing about it is the high performance without the bulk. I haven't thoroughly tested it but I've seen enough to decide to give it to my wife and she absolutely loves it! I'm placin a preorder on the 30w for myself ( as soon as I can find that link) and will (maybe) wait to see how the 50 performs before considering it. It is definitely a nice upgrade from her VV3. Maybe she will get her nic fix now because she has a habit of just puffin on her VV3 and egos like a cig. She gets a much better draw with it. I'm more than happy and I agree you can't beat it for the price. Thumbs down on P Busardo
