I expected an upgrade from the original D'lites and was pretty disappointed. The tips are ok and fit
well enough and are made of a softer material than the originals. You can actually trim these to fit
your thumb getting a better fit than the hard original tips. The light is as bright or brighter than
the original but the issue is that the light unit will not stay attached inside the thumb. I don't
have a solution to make them stay attached. If anyone else has an answer please let me know. If I
were the company, one of my priorities would be to find a way to fix this issue.
