More thoughts after a days use....
it's not the quietest tank around... I like the medium sized insert best and if you reduce the size of the outside hole a little that seems to quieten it down a lot, so maybe it's just a case of balancing the airflow coming in with what's coming out.
filling it is still a bit of a pain sometimes, but no worse than the corolla really and that never put me off that, so....
obviously if you squonk fill it then that doesn't matter anyway.
I love how it looks and coiling it is really easy, flavour is as good as anything else I use, screws are small so make sure you use the right sized screwdriver.
If I lost all my corolla 1.5's then this would be a very suitable replacement and it has some of the features I would have wanted to see on a corolla V2, like the squonkable tank fill, and a better designed deck. I really like the deck, it's probably my favourite thing about it.
There isn't really much I would change to be honest, the fill hole I guess.... I'm not a big fan of either of the supplied tips but that was easy enough to sort out with a different one from the Furai kit. This is what it looks like with the acrylic (?) bubble glass, it's not really a bubble but it does curve out so the tank section is now flush with the cap and base.
BTW, the mod is the Wismec CB60, which was on flash at gearbest for £15 a while back.... a really nice and simple little 60w built in battery mod.
