They are terrible for fingers!
You get only two sizes: 8 small and 2 large clips in a package that are really too big for women's hands. I prefer to use squares of cotton pads cut to size to avoid wasting remover and these clips will not stay put unless I use a piece of foil to shim. If I were to soak a whole cotton ball in remover, it would fit okay but then I would use 3 times as much remover! They seem to work okay for feet though and better than trying to wrap tin foil in between toes.
I don't know about the $50 brands but the cheap $10 ones were a waste of my money. They are the the exact same style pictured above. I prefer using foil any day for the best fit, less evaporation, less wastage and besides, it's just one more item to clean, sanitize and clutter up your workstation.
Photos: The finger with no polish is my "pointer", the one with polish is my "pinkie" and of course, you can tell which is my thumb.
