Can't agree more with your review it is a fabulous tank, it's so well made, nothing gimmicky, just fantastic build quality.
I'm running it with the dual 0.5 ohm SS coil @ 60-65w and the flavour I'm getting is quite simply astounding me.
I watched a lot of reviews for this tank and the freemax starre before deciding to go for the Crown and I'm glad I picked this. I really don't think I could be happier with anything else.
I don't build my own coils so can't comment on the rebuildable option, but if you are looking for an upgrade to a top fill sub ohm tank I can recommend you give this serious consideration, especially for around £25 I don't think you can go wrong. also reviewers have been saying the coils last a month another plus, I've been running this one for 10 days and the flavour and vapour still seem the same as it was when new, no drop off at all.
I'm very interested to see what Uwell bring out next as this is their first attempt at a tank, and it's simply great.
