Samsara playing tips?

So....I recently ran across samsara playing tips...not the break tip. Does anyone have any experience with these in regards of install, mushrooming, how well they hold shape, playability, etc.

I like their break tips (good, but I always prefer the white diamond).... And am thinking of giving these a whirl... But figures I would see if anyone has hands on experience with them yet?

Thanks in advance.
