What clips do you use for your smaller lights...?

I have been looking for a few option to "clip" my lights onto my keys or wherever I ,ay find necessary. Was wondering what you guys use or have found to be reliable and cost effective...?

I see CN quality goods have these ones available which look pretty decent for the price. Thoughts...?
