The mod itself is quite powerful. 50 watts. They say it is off by a bit, but I can not notice.
It's a Sybtank Mini with a matching mod. If you already own a Mini like I do. Then there is no need to update. You can always drill 2 holes on the sides of the RBA deck. If your handy. But for the 58.00 price That I paid for the iSTick back when. This is way more worth that amount of paper! battery change charger and a matching subtank mini redesigned and works flawless if wicked correctly.
