I'd normally preface it with an early day's warning but as I've said the lites have been constant since arrival. Yes they seeped a tad from the 510 (less so with the mtl pin)
But when I found I had five clones within a few months I started to replace them with genuine one's so now have five genuine og lites and the new plus.
the new one does not seep (nor will it, the design prevents it) and the airflow is superb.
I shall now slowly (as funds allow) replace the bases of the others.
I like the fact you get the larger poly tank included with drip tip now.
hands down, best tank I own.
I will add. When fitting the extension and poly tank, lube your o rings first with vg or liquid. They can easily pucker on first fit if dry and your rushing.
