Theracup vs. Revo Cupping device?

Wondering if anyone has used both and can compare? Can't seem to find any comparisons online. The Theracup is significantly more expensive ($150 vs. $60) and wondering if it's worth it? I've had a Theragun for a few years and it was a great purchase so willing to pay for the Theracup if it's a better product.

Cheers!
