This vape has a Standard Core with stainless steel heater cartridge, but may run a bit cool. Please see our Temp Control Page for information on the 15v power supply with Dimmer or Travel VVPS option. Comes with the standard kit plus an optional LED Screen Dimmer, or you can upgrade to our new Travel Size VVPS unit. For help with vape options, see our Ordering Guide. Hybrid Pear is a soft wood and may have a reduced lifespan due to heat degradation, but is still covered under our standard 2 year warranty. This vape is also a Shorty because it's shorter than our standard vapes, which also puts it at an increased risk for heat damage to the wires and plugs.
