There are good hooks and there are flimsy hooks. The hooks from Effortless Hooks, sold with black and white packaging, are of the good kind.
I've pulled, yanked and attempted to mangle my shower curtain (bathroom sadist?) on these hooks as a test, and it flew with flying colors. I've had lots of shower hooks from various bathrooms, and fact of the matter is that some break and some disconnect themselves from the curtain because of snaps or clips to hold the curtain in place. The Effortless Hooks do neither because they don't have those things.
Perhaps it is all in the design or the hard plastic.
Unlike some hooks that lock into place with snaps or clips that always seem to get disconnected mid-shower, Effortless Hooks are straightforward: you hang the shower curtain on the rounded nub at the end of the semi-circular hook and the curtain does not fall off, no matter what. That's called a good design.
The strong plastic can hold well.
The package of 12 hooks only cost me about two dollars more than the cheapest hooks on the shelf, so I call this a great deal.
I wholeheartedly recommend this brand of hooks to anyone, and I cannot fathom why anyone would want to use clips or snaps again.
