Hi, I've had mine for a couple of days now and sadly I've not had a great experience. Partly this is due to manufacturing issues and also it just doesn't suit my preferred style of vaping (too airy for me).
The manufacturing issue concerns the glass cap, which out of the box was so loose I could take it off without holding onto my squonker. The metal cap on the other hand had perfect o ring tolerance.
I replaced the o rings with the spares supplied and there was a slight improvement, but not enough to entirely prevent eliquid seeping between the build deck and the glass cap - there is visible space there. I tried other spare o rings I have but because of the unusual deck size, nothing I tried helped.
It's not all bad though - the drip tip for the metal cap is very comfortable and the feel of the glass cap drip tip part is sublime. And it looks so cool! In the short time I've used it the glass cap hasn't become full of condensation and droplets like I expected. And the flavour is there for sure with the supplied coil.
If Damn Vape came out with another airflow reducer with more restriction, I would give this another go. As things stand, mine is going back to the shop.
