Anyone use Mirka Polarshine polish?

So Ive had a autobody supply company trying to sell me on Mirka Polarshine polishes. They tell me that their customers love it, its fast, and leaves a beautiful shine. Personally, I dont know anyone who uses it, so I cant get an unbiased opinion.
Does anyone here use it, or know someone who does? Its cheaper than the 3M 3 step system, but money doesnt mean squat if it doesnt perform like they say it does.
Thanks FABO
