Query: These covers pretty much suck

Sturdy, but they don't grip the doorknobs well enough for an ADULT to open. I try to open my children's door to check on them at night, and I make enough noise trying to get it open that I normally startle them awake. I'd feel like an idiot if it weren't for the fact that the covers don't grip on ANY type of handle, which I've tried. We have more than one type of door handle in the house.
