Heat controls range from single-setting tools to multi-setting models (examples include 3, 4, 10 and 30 settings). Listed maximum temperatures include specific values such as 400°F, 410°F, 420°F and 425°F, and one model shows an adjustable range of 360°F–480°F.
Heat-up times vary by model. Common listed times include about 20–30 seconds, 30–60 seconds, and up to one minute; some models advertise rapid heat, for example reaching 360°F in ~30 seconds.
Commonly included accessories are a heat-resistant pouch, a styling guide or instruction manual, a cleaning tool/brush, and occasionally a heat-protective glove.
Single-barrel irons are described as producing classic curls and waves with smooth results, while three-barrel wavers are presented as creating s-shaped or beachy-style waves quickly and with staying power.
