Hi, new to forum but have been using the Halo Triton for several years now. Been purchasing all supplies and replacements from Halo. However, recently I found two other sites that have the starter kits for a fraction of the cost. Actually an entire kit is less than the cost of a battery on Halo. First question is - are these knock-offs or does Halo distribute? I have not been able to find these in the past anywhere else. And next, if so - where do I get parts such as replacement coils, batteries, etc.. other than the Halo site for less? I do see the liquid on ohter sites but again, only recently these starter kits. Can anyone provide some info and links. Greatly appreciated!
