Well the main reason im looking into this one is it seems very similar to a RooR in design and quality. Im going to go check it out tommorow and see if it has those RooR qualities im looking for. But the thing is, I am not sure what exactly to check for in terms of chamber size, glass width, etc. Im pretty sure its no $40-$60 peice cause I did some research on Phires and they arent cheap knock-offs, the ones I found ranged $120-250
