Most people who regularly go back and forth and have a background of ice hockey (and mainly spend their time on the ice throughout the year) have my experience aka the product works. That doesn't mean that there aren't people who have issues with this (or any other) product that works for the majority. You responded to his experience and I responded to your unbelief of the Marsblade "hype." Pretty sure that is permissible around these parts.
I also never said that the transition from ice to inline using a normal chassis was impossible. It's just way more of a transition because you can't emulate the "rocker" action that you have and use in ice hockey (which is pretty significant when it comes to the hockey stride). Then again, if you skate in some funky, unnatural way on the ice, maybe the Marsblade would detrimental to your ice + inline experience 😅.
