But has anyone had any experience with these flywheels?

I've got one that looks pretty much the same as this one in my car, it didn't seem too badly made apart from where the cover bolts were drilled/tapped they hadn't deburred the back side, it hasn't broken yet at ~8500rpm.

I'd ask them how similar it actually looks to the picture 'cause that ain't an RB flywheel.
