Review on Polesilk or PSTfitclub?

I was wondering anyone try the product from PST Fit Club: The Pole Suspension Training or poleSilk? Im living in a place without any pole studio, Im looking for something (PST Fit Club: The Pole Suspension Training or poleSilk), that can help as a spotter when I try to learn hard pole move ie Inverted D,ayesha etc...or even help me in stretching. But I found there are relatively little tutorial in using polesilk for stretching or spotter(anyone have link to share.)???
