I suppose they might work okay on a hard, level floor, with no rugs, cords, concrete seams or other bumpiness.
I just know I had a set and chucked them pretty quick. And getting the game onto them, and off again, is almost as much work as they save.
I also have a pair of pinball skates, but I don't remember the last time I used them!
I use a Harbor Freight lift with a platform I made out of 2x8s. Found the lift at a secondhand store for $35!
