@nnote: It said 2.5 on the vendor's website. You might be right. Whatever. The wicks seem to work fine.
@Flyer: No.
I totally get why you'd recommend that and why you like it, and it might solve the problems I'm having with the taste…but it's supposed to be an easy, simple product……and it does seem to work as designed as long as you don't screw it down all the way (ego twist + thread covers FTW…it goes tight enough to loosen the thread covers and hold it in place like a set screw) and don't like to taste your juice.
There seems to be a very fine line (in terms of voltage) between having any flavor at all and it tasting just a tiny bit burnt……kinda like licking 9v battery terminals to see if it's dead. But, frankly, if the choice is between using a cheap, Chinese thing that needs to be rebuilt and isn't actually made for that…and using cartomizers that I'm happy with……I'l pick the cartomizers.
Also, my 1.8Ω head came in DOA. It looks horribly wrapped and shows OL resistance on my meter most of the time…occasionally flashing lower values that flash by too fast to read…meaning no circuit and possibly an intermittent short…I should see if it has a min-max hold function. Fortunately, though, the other 2 are fine and I was pretty sure I'd only want the 2.4Ω head anyway.
I wanted to like it, and the 2.4Ω head @ ~4.5 V is a good vape (with no taste at all up to 4.2 V…kinda strange tasting at 4.5 V…ego twist FTW, again). I don't mind having to saturate the wick…it's more of a PITA than cartomizers but less than dripping. And it does feel warmer than 8.5W on a carto.
Maybe it just needs to break in some more. Maybe I'll try re-wicking eventually (after I buy a couple more tanks), but I really don't want to bother building a coil when there are so much easier options unless I'm going to get something really good out of it. I will say that I have a saddle valve and an empty tank in my daily kit, and as soon as my new shipment of cartos comes in……this thing is probably going to become a plan B. The only reason it isn't already is because I don't have a clean carto to load this juice in.
Different stokes and all, but for me there seems to be no advantage over cartomizer tanks. It's also only been about 16 hours since I got it, so if there's a break-in period…it's not done yet. And it is a lot prettier in blue than my clear-ish DCT (I decided not to trust smoktech's colored plastic).
Edit: after thinking a bit more, I'm wondering if the first toot/hit/whatever was slightly dry and might have burned the wick. After I finish this tank, I'll change to the 2.8Ω head and see what that does, but I'm worried the Twist won't go high enough to get any taste/sensation out of it at all.
