I have one of the cheaper gimido e-nails (was the cheapest on e-nail.org when I bought it but 2nd cheapest currently). I have their 16mm coil (believe its actually 15.8 but generally referred to as 16). I am looking for a quartz piece that will fit said coil. I ordered one online awhile back but the fit was tight and awkward and the bucket on the banger wasnt as deep as the coil itself. Costs me about 65 bucks to replace the banger with the one that came with the enail, but they come from china - long ship times and thin glass. Not neccesarily looking for cheaper, but cheaper, closer, and better are all areas Im considering haha. Does anyone have a 16mm coil from gimido? Have you found any quartz (banger or nail) that fit the coil in a satisfactory manner?
