Overall not a bad mod for the price. The threading isn't that deep but it is pretty smooth. The engravings are done well. Im not sure how well the black parts will hold up. The main problem for me is the throw of the switch. I was expecting it to be like the Broadside. It is very soft and has a fair bit of travel. I think it may be possible to modify it though with maybe some thicker O rings, or a small piece of plastic glued to the underside of the switch.

Great quality sleeve, especially for the price. The knurling is deep and gives good grip. Feels very ergonomic.

I don't know if Fasttech are now using a different manufacturer or not. The RDA I received seems to be vastly inferior in quality to that which others who have submitted a review have recieved. After installing only the second build I have noticed one of the posts has become wobbly. It no longer makes a solid connection without some fiddling around. As far as I can see there is no way of tightening the post either. I tried tightening the 510 pin but it didn't make any difference. This is the second Petri clone Ive bought from here (Both different manufacturers) and both have been bad. I would avoid this RDA. There are much better out there for the same price.

I have both the Atomic clones from here, this one is the best imo (They are both very good though). If you are after a great flavour atty get this. I think its up there with the Derringer. The reduced diameter means it also looks great on some of the smaller regulated devices that are out now.
