These products are really amazing. Since my first purchase back in 2021, I haven’t used heat on my hair since!
I have both the flower curl and waver curl and use either one every single night to sleep in, finding them comfortable and non damaging.
With thick, waist length hair the curls really hold all day compared - to using heat and only getting a few good hours

I have also had incredible, kind and quick customer service from Yanika when purchasing spares too. I would recommend to anyone looking for the perfect bouncy, voluminous curls!

Not worth it if your hair is like mine. I have medium- thick hair. Longest is bra strap length but I also have layers around shoulder length.

Contraption stayed in over night. I had 5 rings and used the claw clips and bobby pins.

A few kinks and best in my hair. Might have worked better if my hair was the same length throughout.

Expensive for what it is...

This product is a £10 tool at best, I really don't know how they're charging £30+ for it. I bought both the bun waver and the flower curl, and was really disappointed with the results. I gave both a good go a few times, following all of the instructions carefully, but the results were only so so. They also hide reviews that don't match their tiktok aesthetic - I commented on their Instagram posts with my true feedback and have since been blocked. I emailed them with my concerns about the product, and got no response.
2 stars because the donut and rings are made of good materials, and it does come with clips and pins you need. Still not worth it though.
If you want to try this idea, you can buy a hair donut and a bendy foam roller and it will do the same thing.
Save your money and don't believe the hype.
