Which balancer?

Mopar Chrysler SB 318 340 360 7.25" SFI Approved Fluid Harmonic Balancer Damper | eBay
Anyone here have experience with this balancer? Looks like a Chinese version of the Fluidamper. For half the price of the Fluidamper unit I may give it a try and keep a close eye on things. What balancer is everyone using these days?
Application is a 422” smallblock internally balanced 90% street/ 10% strip.
