Just got the Delta II and the Subtank Mini in the mail today along with the IStick 50W from myvaporstore. I have been vaping since 2012 and have went through a progression of tanks from carto tanks -> evod -> protank -> kayfun lite -> fogger -> lemo drop -> to these and I got to say, this compairs to the jump in performance from the protank to the kayfun. I am a lung hitter and my wife changes from both. The airflow on the lemo drop was great and I will still use it but both these tanks have more airflow and they are both easy to adjust fo the wife to go back and forth. Tanking the bottom off the lemo to adjust was not really an option. Also the replaceable heads perform great and having that option is a awesome plus. I also got the rda deck for the delta II and it comes with the Subtank whick I will use most of the time. Just wanted to share my excitement and if anyone was thinking ablout these two tanks just put another read out there. Love em both. Also would like to say myvaporstore was a good place to order from.
iStick50W is an awesome device for the price. I did a stupid amount of research before I purchased my first setup, and the general consensus seemed to be that the iStick50W was the best bang for my buck. I've been using it for a bit over 5 weeks now and I haven't the slightest buyers remorse. Two complaints: I can't change the batteries myself (haven't done any research but seems you send it back to eleaf and they replace batteries for $20), and the built in ohm meter is only accurate down to 1/10th of an ohm. The second complaint is more of a personal qualm. I don't need an ohm reader that accurate but it would still be nice to know EXACTLY what my coils' resistance is at.
I am also using the Subtank Mini with RBA. The wicking is very finicky but despite my troubles getting the wicking technique down I really like this tank. I never have any leaking issues, it is built incredibly sturdy, and it comes with EVERYTHING you need right off the bat. No Spending $ on additional crap like extra glass, o-rings, screws, etc. It drives me insane when companies advertise their tank with RBA, but you have to buy the RBA separate.
