I got 2 actually, one for me and my partner, to see if there was any big differences.
This is mine https://www.amazon.com/gp/product/B07V7F8QYK It's larger. No real complaints other than you can only tip it up against the wall on the heavier end, which makes it top heavy.
This is hers https://www.amazon.com/gp/product/B0895DRWVY It's a little smaller, but works fine. It's easier to maneuver when tipped up thanks to some omnidirectional bearings built into the edge.
