Diamondhead BUIS sights, anyone use them?

Cruising Utube tonight I came across these BUIS sights, I had never seen them before, they look interesting. But like anything in reality maybe they are not that good, but the concept of the auto ranger looks good. They been out apparently for a few years but never heard of em?

Curious to know if anyone here has used them before or has any knowledge of them from others they may know that has used them?

Like the qd mounts but those iron sight's are interesting too.

I had the Tory version which was similar, I personally found it to be more precise... but the traditional (round) aperture is quicker.
