I'm actually impressed with the RSST. Love the fact that the
tank prevents shorting of the wick by being all enclosing. The insulated wick hole is great too. And the normal screws, and the 'catch' for the coil works well. Unfortunately I wanted one as soon as I saw a review on it, so had to pick one up from a different vendor. One thing that was nice though was that they offered a hole enlargement option to 1.2, 1.3, 1.4 or 1.5 mm (You guys should offer that)..
I'll probably grab another when I make my next order.
