Dyson Airwrap vs Shark Flex style

Hello everyone,

So I'm planning to buy an Airwrap style curler for straight/wavy hair for my wife, have no idea of these tools and found similar offerings from Dyson and Shark. I know the Dyson is definitely premium but I'm wondering if it offers better value for money for what I pay for New especially since it's 2-3 times expensive than Shark.

I'm in Canada and Shark is available on sale for $279.99 and Dyson new for $799 or Refurbished (Excellent) for $439.99. Even if I consider the refurbished option it's still $160 expensive compared to a New Shark. So please drop your opinions and if there's anyone who has tried both let me know your experience and what I should get.

Thanks
