Entry Steps too high at times what do you use?

I carry around one of these, a basic Rubbermaid Step Stool:



IIRC, bought it at a Walmart for about $12. A year or so prior, in a pinch because it was a really big leap, where we were staying, I went to the local closest Home Depot for a couple $2 each CMU’s, that went into the dumpster at the end of that week’s stay. It was cheaper than wrecked knees.
