Can I use it on my Audi Q3 without any problems. At first I was a little worried about possible damage to my car because I weigh 190. So my wife stepped on it and it seemed stable without showing any signs of depression. So I decided to use it myself and wanted to place and adjust our stuff without any problems. We walk a lot in the fresh air and sometimes my boots are covered with dirt (mud, straw) so I was happy to see that the tread was ok. big enough that my shoes don't slip when I step on them. I can also put both feet on it so my balance seems good. The platform you step on adjusts like locking pliers, allowing you to find the sweet spot where it is at ground level. The part that looks like a pull handle is an adjustable foot that sits flush with the door frame to keep it in place (I'm guessing here, but it seems pretty obvious). Overall I would recommend this product. I was happy with the price and even got a discount coupon (I love coupons!) and next day delivery too. Edit: I tried this on my wife's sedan and it worked too.
