I have exactly that sled, bought it about 9 months ago, it’s changed the way I condition significantly.
I push on my asphalt driveway, so I bought the plastic skis to minimize damage (to both the sled and the asphalt), and it’s been great: solid and quiet, well-built, absolutely no complaints.
Edit: I don’t have a rope for pulling, but I want to get one, because I suppose my one complaint is that it’s hard to pull backwards with the default handles. But maybe that’s just because I have short arms or something?
