I was sold these coils as an alternative to the Eleaf HW2 because they were out-of-stock, so I knew nothing about a quad-core or if I even wanted/needed one. Turns out I don't.
The cotton doesn't maintain its absorption and starts mad leaking after only 700-800 puffs on my counter, using 80vg/20pg. I'm guessing this is because these quad-cores are designed for heavy cloud-makers and this destroys the cotton in no time. I was getting 3-4000 puffs of great vapor - same juice - and zero leaking with the HW2's. That's a huge and expensive difference when you don't need a coil to make huge clouds.
I'd like to see this kind of info available when choosing a coil if you don't know any better. There's way too much on the market and no usage details. Maybe I'm wrong on the purpose of this coil type, but I know it's nowhere near a suitable alternative to the HW2.

X4 VS Q2

I'm a fan of the baby Q2 coil but decide to give the X4 a try. I liked the X4 but not as much as the Q2.
Pro The X4 have warmer vape on lower watts and longer puff than the Q2 The flavor feel stronger It last longer than the Q2 for me
Con X4 have less airflow than the Q2 X4 have a little bit more dry hit on 90%+ VG on long puff than the Q2
Overall it's a realy good coil that I would recommend for lower than 90$ vg lover.
