I bought 3 of these - 2 for our downstairs hallway and 1 for the upstairs landing. We had lampshades previously which didnt give off much light. These pendants have totally transformed both areas and the light they give off has made such a difference.  The pendants themselves feel more like hard plastic than glass and some had some tiny air bubbles in but it wasnt enough to notice once they were hanging. The flex is very long so we did have to shorten them considerably. Overall, we are very pleased, they look modern and contemporary which is what we wanted and the price was great.
