I have Zephyrus V2 and it taught me a good lesson. Never use best juice when you receive a new tank.
When I got Zephyrus I installed 2 coils, wicked as I saw on youtube, filled with last 5ml of my best juice and then I wiped all the juice from my desk.

Don't get me wrong, it's a great flavorful tank you can DL or MTL and holds 6ml of juice. But wicking is PITA. Even when I thought I mastered the tank on some occasions it still leaked or it just didn't wick fast enough. You have to use just enough cotton to fill the holes. It means trimming the cotton to shape, using thin screwdriver to place just enough cotton over and in the holes, maybe trim again... and then you have to pray it will not leak and that it will wick fast enough. When wicked perfectly it's a really great tank and this is the reason why so many people still use these tanks (Goblin has same problems). Taste for me (2x2,5mm coils 6 wraps SS316L) is on par with with Rose3 and Taifun GT3 I use now. But with these tanks I can use only 1 coil and I can rewick in 5 minutes. And if there is a problem with wick, it can be fixed with juice flow control. And this is the reason that Zephyrus V2 is in a box cleaned, rewicked and ready for use ever since I got these easy maintenance tanks.
