Vibrating scraping board gua sha, a failed purchase made with my own money

I bought a vibrating scraping gua sha on AliExpress.

I bought this with high expectations because I heard it can be used not only on the face but also on the body like arms, legs, and abdomen, and that it has up to 12 vibration levels!!!

I'm ruined...

I increase the vibration intensity, but why does only the main body shake and not the actual area being used feel cool? 😂

My hands were shaking like crazy and it was so noisy that I just turned it off and am using it like a regular gua sha.

It's just easier to use it as is... I think the success rate on AliExpress is 50/50.
