Even if the spin gym was the second coming, I wouldn't buy one from that overbearing, obnoxious, patronising woman. She's made enough money from it already IMO. I would also not buy any of the other stuff she's flogging, from QVC or elsewhere.
They have other US fitness guests - like Bodyblade Bruce, and the guy who comes over with the inversion table - both older guys, and both able to explain their products without bellowing and browbeating their audience.
