Aixiz's G2 is much cheaper, but the threads or OD are slightly larger and don't fit into LasershowPart's brass or copper diode mounts. If you are using DTR's 12mm diode modules, both G2 lenses fit just fine (Aixiz's G2 requires more plumbers tape, of course).
The diode housing does heat up and power drops, but I haven't polished it yet.
Polished what? The diode housing should have a bit of thermal paste as should the mount to optic plate contact point, but I don't know what one would polish.
