PBU hi-compression dome for C1?

Had anyone already tried the PBU hi-compression dome?
I saw the pictures and it looks like the original chinese part!

Is there any review or opinions about it?
Thank you,

I have the new the dome, it is the same as the old one but it has a different dome, higher compression. It does add to compression, there is a difference.

OK...
They also say it has more compression...

But is it really true?
Do you notice any differences?

For sure, the compression is higher, i didnt get the bronze dome though, but it is mod that does help.

I made my own dome from h15 alloy and fitted it on my bike. Its around 15:1 and with a 1mm base gasket, 3mm reed spacer, and rocket key the performance is awesome. I'm planning to add a 18mm carb soon. Nothing at our local track can touch it on pure acceleration.
