I got this thing, and its my first foray into enails, altho my friend has the more common box-wired kind with temp controls. But even he likes this thing. The hits i get from this are amazing and i feel like it saves me 5x the bho vs an actual "torch" I do love it. I see my friend using a "typical" enail still using a torch sometimes with the quartz banger while its attached to the temp box. He does it for a few seconds to finish the bowl. For me, im trying to avoid the whole butane torch thing. Anyway, of course much more than the purchase price goes into buying nails like the Dr Dabber. They wont stay clean forever. But ive managed to make 2 nails last maybe 2 months so far. I also tried it with greens, with a pancake. Def not anything like firefly2 or any pro herb vape. For me, the main thing is, the way that its built with all the o-ring/bands. It seems to me you cant replace the very base, which def needs cleaning here and there, and i havent found replacements for the rings, which also are very important to the unit's functioning. Has anyone been able to find either replacement rings or a replacement base? Thanks, really would appreciate it. Also been thinking about a Yocan pen, maybe Evolve XL or Nyx. Or the Dr Dabber erig though for now it seems this works as a good erig. I just need to find those replacements!
