These were an interesting purchase because I really wasnt sure what to expect. Aside from the fact that these were a little big for me- I have small hands so it wasnt a surprise- these are pretty bright. They dont cover all your fingers just two, and then the gloves strap around your wrist to stabilize them.
Each finger has a light on it so you technically get four little beams to point wherever you are working which I think is awesome. I dont see how you can blind yourself either because you wouldn't ever have your hands facing that way, you would have to have your palm flat facing down and pointed at yourself in order to do that and that would not be comfortable
The material is good too. It wasnt really thick because these aren't meant to be actual gloves.
