Review (3/5): Quality commensurate with price, but beware sizes
The sizes on these are strange. People's fingers vary a lot in size, obviously, and this is a set without any specific sizing information, so I didn't expect them to necessarily fit all my fingers correctly. But the way they didn't fit was surprising. The largest two barely fit on my thumb--if I push it down enough not to fall off, it cuts off my circulation. The smallest two fit on my pinky well, maybe a little small. The others, which you'd expect to be between those sizes...well, they are between those two sizes, but they're almost as big as the thumb ones. A person with a thumb that size...there's just no way their ring, middle, and pointer fingers would be that huge.
Anyway, it's better for them to be too big than too small. If you push them down they don't look good, but grab something similar to foam mounting tape (https://www.amazon.com/3M-Heavy-Mounting-1-Inch-50-Inch/dp/B00004Z4A8) and pad the top inside of the rings that are too big. It makes them more comfortable, too!
That makes the only problem child in my set the thumb.
