The Plenty is a handheld whip vaporizer made by the same people as the Volcano vaporizer (Storz & Bickel). Though it may look like a power tool, it's surprisingly light-weight and silent. The Plenty can actually be operated by one hand, but unfortunately can't be used without a plugged in power cord, so it's not portable.
The circular or double helix pattern of the stainless steel whip ensures much more efficient vaporization and air cooling. This bad boy heats up to 130 °C within a minute. The maximum temperature is around 200 °C. The current temperature is displayed clearly on the analogue thermometer on the front of the vaporizer.
