Ive got one, its italian, not sure of the manufacturer - the logo is a little elephant.
it has rubber feet & a brcket the slips round & under the boot lip, although the feet do need extra protection, as they ruined the paint after being left on for 6 months - I needed the boot resprayed anyway.
I needed to adjust the boot springs to their strongest setting.............but remember to re-adjust them after removal.........otherwise you boot has a tendancy to want to launch itself into orbit.
