Auto-cycle is an option on the Laifen to rotate between all the temp settings. This allows quick bursts of hot, warm and cool air to ensure the hair doesn’t overheat. Also - the color rings on the back of the dryer make it easy to see which temp setting I’m on so that I don’t need to keep bringing the diffuser down to look at it. I can easily see the reflection in the mirror or against my hand. 10/10 recommend!
