What is the difference between Whisper Flex 1 and Whisper Flex 2?

Whisper Flex 2 is the latest version and offers more settings than its predecessor. For example, it has 30 speed settings instead of 26, touch controls instead of a rotary knob, and an adjustable oscillation angle.

In addition, Whisper Flex 2 is slightly taller than the Whisper Flex Smart. Both models are quiet in use and can be operated by remote control or through the Duux app.
