0.5 are game changers (28 September 2016)
For me, the 0.5 coils are a game changer. The 0.4 coils are, pretty much exactly the same as the Cleito 0.4 coils. Solid flavor, nice airy draw and decent longevity.
Where the EVO tank comes into it's own is with the 0.5 ohm coils. The way the coil itself is designed results in a tighter draw, although still providing a very comfortable lung hit. The tighter draw results in a more condensed vape, therefor boosting the flavor. I get better flavor with the 0.5 ohm coils at 35 watts than I do with the 0.4 ohm coil at 50 watts, with the trade off being a slightly more restricted airflow and slightly less vapor production (which is a plus point for me).
Anyone that has a Cleito, uses the 0.4 Cleito coils and expects the 0.4 ohm coils for the Evo to be completely different, is wrong. I can't find any difference in flavor or vapor production between the two. But anyone coming from a Cleito / EVO 0.4 coils that wants a true boost of flavor, pick up the 0.5 ohm coils.
A word for coil longevity too. The 0.5 coil lasted me over 80ml of sweet, sugary, American, 80VG juice before the flavor dropped off. Another 0.5 coil, vaping on a 70VG, less sugary, UK based, liquid has lasted me 100ml so far and is still going strong.
