Honest reviews of the Bur Bur Mermaid Brush?

Hi! I've been eyeing the Bur Bur Ludmila Essential Boar Bristle Brush (Mermaid Brush), but all I can find are paid partnerships promoting the brush. This makes me a bit skeptical, especially as the brush is quite expensive. Has anyone here tried it, is it actually as good at detangling and providing shine as they say?

(For context, I have fine and wavy hair.)
