Good flavour for me, tbh sets the standard for my RTA's to emulate but that is just my personal opinion/taste
If you buy tank new, see if you can perhaps get the 4ml 24mm version than the 2ml (or 3ml 22mm version maybe)
Coils are about £1:50~£2:00 if you shop around and should last 2~4 weeks or so at a push (if you rinse 'em and squeeze a bit more life)
The Zenith Kroma kit is worth a punt, even the coolfire mini D22 kit too if you want something smaller in a kit
The Zenith may not tick all the boxes for EVERYBODY but imho it comes pretty close and you could buy a LOT worse for ya money
Hence the reason why it is highly rated/recommended very often by MTL vapers
Coils - well there are 1.6, 0.8, 0.5 & the recent 0.48 coils - after a bit of experimenting I seem to like 0.8 Ohm coils @ 13.5~14w
short answer - yes it is pretty damn good, the Zlide offers nothing new imho & you gotta remove tip every time to fill the Zlide
with no larger 4ml version available and only a slight modest price saving - yeah I'm in no rush to buy a Zlide over my Zenith's....
Though looking at the Zlide drip tips, they seem to have an extra lug at bottom, which might be part of child lock
If anybody has a Zlide, perhaps they could try a regular tip in there to see if it no longer locks shut
Or trim off the extra lug at bottom, then you might not need to keep removing the tip every time you refill it
pic says 1,000 words as they say, the Zlide's drip tips from AliExpress, with "extra lug" at bottom....
