This is the only product thus far that I've been dissappointed with. I purchased it along with a 20" light fixture (a metal stand). The stand has a little hook on the end, which the light fixture rests on. The metal hook burned THROUGH the light fixture. Not only could this have started a fire by dripping hot metal into the enclosure- this ALSO could have seriously injured my tort. I give it two thumbs down. . . . . . I have since purchased a different light fixture that is porcelian instead of metal- and absolutely love it. . . .no problems, no melting, no potential house fire. . . . . .*wipes brow*
