I have the Shark FlexFusion and I really love it. The straightener function works really well but I do use it along with other attachments (e.g., the curling or the brush style attachment) to finish off the look.

I hated the Airstraight FWIW. Its not good if you have thick wavy layered hair, it makes your hair look straight but chunky. Not a flat ironed look.

There are no dupes, unfortunately.

Looking for a less expensive version of the Dyson AirStrait (not AirWrap) to take to Europe. The Shark FlexStyle seems too complicated with all the different pieces. I’d like something more similar to the AirStrait. Any recommendations?
