Has anyone tried Young Shine (Blue Sponge, Yellow Sponge)?

Sooo, basically I was looking in the massive hole of TT equipment, and I stumbled upon this:

I have several questions here:
1: Has anyone tried it?
2: If so, can you compare it to any other rubbers in terms of Spin, Speed and Control
3: I read a blog about this Russian guy, that apparently got a bubble in his after in less than a week. Can anyone confirm this?

Any information, or rumours would be highly appreciated!👍
