Bought this blind as there were no reviews but the design appealed to me. This is worth the money. Well constructed, all O rings have just the right amount of tension to hold it all together, easy enough to build on and for a 24mm RDA, flavour is excellent. Airflow is adjustable, with an independent bottom barrel, which allows the airflow to be closed down but still be centred to the coils. This may not appeal to those who like wide open airflow as there is a bit of restriction when fully open, roughly the same as a Drop RDA with the top row closed off. Couple of subjective negatives for me personally. The juice well could have been a touch deeper, another 1mm would have been ideal and the supplied drip tip, for me is a non starter. An 810 fitting drip tip with a bore that is less than some 510's ? doesn't work for me. As I said these are subjective negatives and certainly not deal breakers. I'd willingly buy another in a different colour were it to become available.
