Ok I was not really at first impressed that on the smok you do not set wattage, just min, soft, regular, hard, and max.
I find on soft it works perfectly, connected to bluetooth the watts actually jump around to get it to temp, and when at temp puts out like 9 to keep it at that temp, and it continues to produce, and there is NO dry hits at all.
I am using my sigelei, and at 35 Watts and 240C, you can detect the smallest hint of dry hit. I am going to test the IPV next, see how well that performs with the dripper, and if it has better/worse TC than the Sigelei. But, The smok seems to top them all, with no dry hit at all, so much so you can forget to redrip as there is no burn at ALL.
I think just setting the temp is actually better, and letting the device control wattage itself works better, at least with the mods I have it does. (so far, I am going to test the IPV D2 now)
EDIT: Ok, the IPV D2 does the TC better than the sigelei, I would say on par with the Xcube 2. I am using that at 30 Joules/watts (Chinese just converted watts into joules with no changes, just renamed it, so 1 watt is one joule.
I think it is my most impressive TC device, although I think they are all great devices. From now on I see no reason not to make the majority of my builds with NI200 and use TC, as 3 of my 6 mods can do it, I will keep some drippers and one tanks set up with kanthal (Most likely the subtank) and the rest NI200.
I am feel like I have met a revolution, Temp control that actuallly works for me, and I can enjoy MORE than standard watt mode due to know burning when juice gets low.
I love it.
