Question Thermal Grizzly Duronaut ??

New kid on the block but a google search reveals nothing. Anyone with experience or any proper reviews ?. Thermal Grizzly website says little as usual.
Looks like it's pretty new, perhaps no one has reviewed it yet. I do love how the product description goes into very specific detail on....the components of any thermal past (silicone oil, aluminum, other stuff). A thermal conductivity number would be nice at the very least..
