I just noticed the exact opposite today as I tried my first fluxomizer.
Previously I was using Boge LR cartos, they seemed to work well at first with great taste and decent vapor, but they quickly drop off in performance and are mostly useless by the 2nd day (regardless of what juice I am using). Sure they still work, but the flavor is muted and there is a strange burnt taste lingering.
Well after filling up my fluxo today I am absolutely blown away at the performance. LOADS of vapor compared to the LR Boge's, and even had a better TH as well (not as harsh and more fulfilling). Seriously, vapor production is like the difference between vaping 100% VG vs 100% PG.
Using the same juice, my fluxo is delivering 2 times more vapor, easily. And you want to know the strange thing about that? These fluxos are reading at 2.8-2.9 ohms, my LR Boge's always read about 2.3 to 2.4 ohms. So not only are these higher in resistance, but they are producing tons more vapor. I can only imagine how insane the LR fluxos will be!
And taste? Well aside from a underlying metallic taste (which to me is akin to using attys) that I hope will go away soon, the flavor is much more pronounced in my fluxo. The sweetness comes to life and the vapor is much warmer and more satisfying.
So far I am very impressed, but since I just started using these today I am not sure how they will fare in the long run. But they are easy enough to clean and should last much longer than my Boge's.
Oh and I did do a bit of tinkering prior to fill-up. I just popped off the plastic sleeve, fluffed the wick a bit (just pulled it up a tad bit further on the ceramic plate) reversed the main seal-plug thing, and stuck my drip tip in (my fluxos didn't come with the 2nd inner seal, it was just the main plug and the black piece you remove from the top). I also did some dry-burning as well prior to filling to get rid of any Chinese primer that may have been on there, and it definitely burned something off.
Not sure how they would have worked without the adjustments, but it works amazingly well now. This thing wicks like a champ, I've nearly almost emptied my 0.8ml capacity in no time at all. And even being nearly empty when I look at my wick, it's still soaked to the bone glistening with juice.
Although the one problem I am pretty sure I will have is that this thing looks as if it will leak like crazy, just tipping it upside down for a second gets the area underneath my drip-tip pretty wet. So I will have to see once I try carrying this how much leaks out in a given day and how messy it may get.
But that aside, being able to see my juice level is amazing! I always hated that about traditional cartos, never being sure how much juice is left. And tanks don't work very well either, plus you still have unknown amounts of juice in after the tank runs dry.
