This was my first rta and I have to say I'm loving it. Grub screws are crap and had to change a couple out of the pre-installed ones. But that's nothing major since for my coil builds I just use my rda. Small leaking after fill up but nothing serious. Wanted something I could use at work and not be scared to break it and waste 30-40 bucks. So the 11 I paid plus shipping definitely worth it.
