I haven't owned these steps but know they are very stable but pricey. If money is no object they are very good. However, you can buy/make a brace to hand place under the factory steps that makes them quite stable for next to nothing. If you need a different geometry on the steps for medical reasons, some of the aftermarket steps are wider, have an extra step, etc. and may be worth the money. As an acquaintance of mine says, "It only costs 90% more to go first class."
