The main difference between the Laifen Swift Premium and the Swift Special lies not in the temperature levels, but in the following aspects:

- Colour choice and design: the Swift Premium often has a more elegant finish, such as a gold-trimmed design, while the Swift Special is available in other colours.
- Accessories: the Swift Special comes with three attachments (a standard nozzle, a diffuser and a quick styling nozzle), while the Swift Premium only comes with a standard nozzle as standard.
- Temperature settings: Both models actually have three temperature settings and two speed settings, there are no four temperature settings.

There is no indication that the Swift Premium has four temperature settings, while the Swift Special only has three. Both models are identical in most technical aspects, with the aforementioned differences in design and accessories.
