v4 Concentrate Heater

The v4 came before the v5 and plenty of people are still running one, so everything to keep it going lives here. Titanium and quartz cup and donut coil setups are ten dollars, the polished silicon carbide crucible cup is here for more thermal mass, and there are four packs of replacement donut and cup sets in 10mm medium and 13mm large that also fit the v3.5 and SAI heaters. The steel and glass vortex tops are shared with the v5 and the Cub, as are the hydratubes and the 510 extension cables. The v4.5 with the polished silicon carbide heater is in this category too, on its own or bundled with an iStick Pico Plus. If you are buying new today we would point you at the v5, but nothing about the v4 has been discontinued or orphaned and it is not going to be.
